In this case the linear equations are given:
A company offers two data plans for cell phones. The plan A the linear function for the
charge is given by
y=10x
where x represents the total number of megabytes. The Plan B charge is calculated using
the linear function
y = 4x + 75.
How many megabytes would a customer need to use for Plan be to be a better deal?
1) more than 12.5 megabytes
2) less than 18.75 megabytes
3)
Plan b is always a better deal because the charge per megabyte is less than in
plan A
4) More than 10 megabytes.
5) More than 20 megabytes
The customer would need to use more than 12.5 megabytes for Plan B to be a better deal. (Option 1) more than 12.5 megabytes).
To determine when Plan B would be a better deal than Plan A, we need to compare the charges for both plans based on the number of megabytes used.
Plan A is represented by the linear function y = 10x, where x represents the total number of megabytes used, and y represents the charge for the plan.
Plan B is represented by the linear function y = 4x + 75, where x represents the total number of megabytes used, and y represents the charge for the plan.
To find the point at which Plan B becomes a better deal, we need to find the x-value where the charge for Plan B is less than the charge for Plan A.
In other words, we need to find the x-value that satisfies the inequality:
4x + 75 < 10x
To solve this inequality, we subtract 4x from both sides:
75 < 6x
Then, we divide both sides by 6:
12.5 < x
Therefore, the customer would need to use more than 12.5 megabytes for Plan B to be a better deal.
This means that option 1) "more than 12.5 megabytes" is the correct answer.
For any value of x greater than 12.5, the charge for Plan B will be less than the charge for Plan A, making it a better deal for the customer.

The sum of three numbers $x$ ,$y$, $z$ is 165. When the smallest number $x$ is multiplied by 7, the result is $n$. The value $n$ is obtained by subtracting 9 from the largest number $y$. This number $n$ also results by adding 9 to the third number $z$. What is the product of the three numbers?
Answer:
Step-by-step explanation:
Let's break down the given information step by step to solve the problem:
The sum of three numbers x, y, and z is 165: x + y + z = 165.
When the smallest number x is multiplied by 7, the result is n: 7x = n.
The value n is obtained by subtracting 9 from the largest number y: y - 9 = n.
The value n is also obtained by adding 9 to the third number z: z + 9 = n.
We can use this information to form a system of equations:
Equation 1: x + y + z = 165
Equation 2: 7x = n
Equation 3: y - 9 = n
Equation 4: z + 9 = n
To find the product of the three numbers, we need to determine the values of x, y, z, and n.
First, let's solve for n using Equation 2:
7x = n
Now, let's substitute the value of n into Equations 3 and 4:
Equation 3: y - 9 = 7x
Equation 4: z + 9 = 7x
We can rearrange Equation 3 to express y in terms of x:
y = 7x + 9
Now, we can substitute the value of y in Equation 1:
x + (7x + 9) + z = 165
Simplifying:
8x + z = 156
Now, we have two equations:
Equation 4: z + 9 = 7x
8x + z = 156
We can solve this system of equations to find the values of x and z:
From Equation 4, we have z = 7x - 9.
Substituting z in Equation 8x + z = 156:
8x + (7x - 9) = 156
15x - 9 = 156
15x = 165
x = 11
Substituting x = 11 in Equation 4:
z + 9 = 7(11)
z + 9 = 77
z = 68
Now, we have the values of x = 11, y = 7x + 9 = 7(11) + 9 = 86, and z = 68.
The product of the three numbers x, y, and z is:
Product = x * y * z = 11 * 86 * 68 = 64648.
Therefore, the product of the three numbers is 64648.

Answer:
x intercept : -1
y intercept : 3
Step-by-step explanation:
We have 3x - y = -3 ---eq(1)
The x intercept is the value of x when y = 0 in eq(1),
⇒ 3x - 0 = -3
⇒ x = -3/3
⇒ x = -1
The y intercept is the value of y when x = 0 in eq(1),
⇒ 3(0) - y = -3
⇒ -y = -3
⇒ y = 3
Para tener una sucesión es imprescindible que los números que lo forman :
A: sean infinitos
B: tengan una ley de formación C:estén ordenados
For a collection of numbers to be considered a sequence, it is essential that they have a law of formation, are ordered in a specific manner, and can be either finite or infinite.
B: They have a law of formation:
A sequence is a set of numbers arranged in a specific order according to a rule or pattern. The numbers in a sequence are not random but follow a specific law of formation.
This law can be a mathematical formula, a recursive relationship, or any other systematic pattern that determines the values of the sequence. Without a well-defined law of formation, a collection of numbers cannot be considered a sequence.
C: They are ordered:
In a sequence, the numbers are arranged in a specific order or sequence. The order of the numbers is crucial and defines the pattern and structure of the sequence.
Each number in the sequence has a unique position or index that determines its place in the sequence. The order of the numbers allows us to identify the next number or predict the pattern of the sequence. Without the concept of order, the numbers would simply be a set of unrelated elements and not a sequence.
A: They may or may not be infinite:
Sequences can be finite or infinite. A finite sequence has a specific number of terms, and once the pattern or rule is established, the sequence ends.
On the other hand, an infinite sequence continues indefinitely, and its terms extend infinitely in one direction or both directions. Whether a sequence is finite or infinite depends on the context and the specific rule or pattern that governs its formation.

Bronson Building Inc. is considering a possible investment project, consisting of constructing an office building and then renting it out for use to various local businesses. The initial cost of acquiring the land and constructing the building (first cost) is $21,000,000. The building is expected to be sold for $2,000,000 in 23 years, at the end of the last year of the project. Annual revenue from collecting rents is expected to be $4,000,000, while annual maintenance and operating expenses are projected to equal $2,000,000. Using MARR of 10%, compute the present worth of the project. Note: if the present worth is negative you must include the negative sign with your answer
Answer:The present worth of the project for Bronson Building Inc is $6,389,137.
In order to calculate the present worth, follow these steps:
1. The given information is:
Initial cost (first cost) = $18,000,000
Annual revenue = $5,000,000
Annual expenses = $2,000,000
Net annual cash flow = Annual revenue - Annual expenses = $5,000,000 - $2,000,000 = $3,000,000
MARR = 11%
Project duration = 18 years
Sale price at the end of the project = $8,000,000
2. To calculate the present worth, we first need to find the present value of the net annual cash flows using the MARR as the discount rate. Then, we will add the present value of the sale price and subtract the initial cost.
Present value of net annual cash flows (PV_ACF) = Net annual cash flow * [(1 - (1 + MARR)^(-duration)) / MARR]
PV_ACF = $3,000,000 * [(1 - (1 + 0.11)^(-18)) / 0.11] = $3,000,000 * 7.696 = $23,088,000
3. Find the present value of the sale price at the end of the project.
Present value of sale price (PV_SP) = Sale price / (1 + MARR)^duration
PV_SP = $8,000,000 / (1 + 0.11)^18 = $8,000,000 / 6.146 = $1,301,137
4. Calculate the present worth of the project.
Present worth = PV_ACF + PV_SP - Initial cost
Present worth = $23,088,000 + $1,301,137 - $18,000,000 = $6,389,137

Relative maximum at x=0; Relative minimum at x=8/3
Step-by-step explanation:
To find the relative maximums and the relative minimums, you must first find the first derivative of the function. The first derivative of this function is 6x^2-16x. Simply it and you get 2x(3x-8). X would be equal to 0 and 8/3. Next, make a number line where you put 0 and 8/3 have a value of zero.
+ - +
-------------------0----------------------------8/3-----------------------
Plug in a value of x<0 to get the region left of 0. Say we use -1, we get -2(-3-8), which is positive, meaning that it is increasing there. From 0 to 8/3, if we use 1, we get 2(3-8), which is decreasing. If we use 3, we get 6(9-8), which is increasing. From this, we can see that when x=0, the graph has a relative maximum. When x=8/3, the graph has a relative minimum.

The completed sequence would then be: 2, 4, 7, 9, 16, 19, 29.
To complete the given number sequence, let's analyze the pattern and identify the missing terms.
Looking at the given sequence 2, 4, 7, __, 16, __, 29, __, we can observe the following pattern:
The difference between consecutive terms in the sequence is increasing by 1. In other words, the sequence is formed by adding 2 to the previous term, then adding 3, then adding 4, and so on.
Using this pattern, we can determine the missing terms as follows:
To obtain the third term, we add 2 to the second term:
7 + 2 = 9
To find the fifth term, we add 3 to the fourth term:
16 + 3 = 19
To determine the seventh term, we add 4 to the sixth term:
__ + 4 = 23

Given that √x + √y=138 and x-y=1656, find x.
The value of x is 5625 when √x + √y=138 and x-y=1656.
To solve for x using the given equations, we will use the method of substitution. Let's go through the steps:
Start with the equation √x + √y = 138.
We want to express y in terms of x, so solve for y in terms of x by isolating √y:
√y = 138 - √x
Square both sides of the equation to eliminate the square root:
(√y)² = (138 - √x)²
y = (138 - √x)²
Now, substitute the expression for y in the second equation x - y = 1656:
x - (138 - √x)² = 1656
Expand the squared term:
x - (138² - 2 * 138 * √x + (√x)²) = 1656
Simplify the equation further:
x - (19044 - 276 * √x + x) = 1656
Combine like terms and rearrange the equation:
-19044 + 276 * √x = 1656
Move the constant term to the other side:
276 * √x = 20700
Divide both sides of the equation by 276 to solve for √x:
√x = 20700 / 276
√x = 75
Square both sides to solve for x:
x = (√x)²
x = 75²
x = 5625
Therefore, the value of x is 5625.
By substituting this value of x back into the original equations, we can verify that √x + √y = 138 and x - y = 1656 hold true.

Need Help
Answer: -27
Step-by-step explanation: Use inductive reasoning to predict the most probable next number in the list.
3, 9, -3, 3, -9, -3, -15, -9, -21, ?
We can start by looking at the differences between consecutive terms in the list:
9 - 3 = 6 -3 - 9 = -12 3 - (-3) = 6 -9 - 3 = -12 -3 - (-9) = 6 -15 - (-3) = -12 -9 - (-15) = 6 -21 - (-9) = -12
Notice that the differences alternate between positive 6 and negative 12. This suggests that the pattern involves adding 6, then subtracting 12, and then adding 6 again. Applying this pattern to the last term in the list (-21), we get:
-21 + 6 = -15 -15 - 12 = -27 -27 + 6 = -21
Therefore, we predict that the most probable next number in the list is -27.
A student is applying to the University of Florida (UF) and Florida State (FSU).
There is a 40% chance of being accepted at FSU. If the student is accepted at FSU, the probability of being accepted at UF is 60%. If the student is not accepted at FSU there is an 90% chance of non-acceptance at UF.
Of the students not accepted at UF, what is the probability they are accepted at FSU?
Answer:
Let's denote:
- A as the event "student is accepted at FSU"
- B as the event "student is accepted at UF"
We have the following probabilities given:
- P(A) = 0.4 (probability of being accepted at FSU)
- P(B|A) = 0.6 (probability of being accepted at UF given acceptance at FSU)
- P(B'|A') = 0.9 (probability of not being accepted at UF given non-acceptance at FSU), where B' is the complement of B (not being accepted at UF) and A' is the complement of A (not being accepted at FSU).
We want to find P(A|B'), or the probability of being accepted at FSU given non-acceptance at UF.
To calculate this, we can use Bayes' Theorem, which states that:
P(A|B') = P(B'|A) * P(A) / P(B')
We can calculate P(B'|A), the probability of non-acceptance at UF given acceptance at FSU, by using the fact that the sum of probabilities of complementary events equals 1:
P(B'|A) = 1 - P(B|A) = 1 - 0.6 = 0.4
Next, we need to find P(B'), the total probability of non-acceptance at UF. We can use the law of total probability to calculate this:
P(B') = P(B'|A) * P(A) + P(B'|A') * P(A')
P(B') = 0.4 * 0.4 + 0.9 * 0.6 = 0.16 + 0.54 = 0.7
Finally, we can substitute these values into Bayes' theorem:
P(A|B') = P(B'|A) * P(A) / P(B') = 0.4 * 0.4 / 0.7 ≈ 0.229
Therefore, the probability that a student is accepted at FSU given that they are not accepted at UF is approximately 22.9%.

Triangle ABC with vertices at A(4, 3), B(3, −2), C(−3, 1) is dilated using a scale factor of 1.5 to create triangle A′B′C′. Determine the vertex of point A′.
The vertex of point A' in the dilated triangle A'B'C' is (6, 4.5).
1. Start by calculating the distance between the vertices of the original triangle ABC:
- Distance between A(4, 3) and B(3, -2):
Δx = 3 - 4 = -1
Δy = -2 - 3 = -5
Distance = √((-[tex]1)^2[/tex] + (-[tex]5)^2[/tex]) = √26
- Distance between B(3, -2) and C(-3, 1):
Δx = -3 - 3 = -6
Δy = 1 - (-2) = 3
Distance = √((-6)² + 3²) = √45 = 3√5
- Distance between C(-3, 1) and A(4, 3):
Δx = 4 - (-3) = 7
Δy = 3 - 1 = 2
Distance = √(7² + 2²) = √53
2. Apply the scale factor of 1.5 to the distances calculated above:
- Distance between A' and B' = 1.5 * √26
- Distance between B' and C' = 1.5 * 3√5
- Distance between C' and A' = 1.5 * √53
3. Determine the coordinates of A' by using the distance formula and the given coordinates of A(4, 3):
- A' is located Δx units horizontally and Δy units vertically from A.
- Δx = 1.5 * (-1) = -1.5
- Δy = 1.5 * (-5) = -7.5
- Coordinates of A':

Step-by-step explanation:
Evalute 3n² - 8n - 9, given n(n - 3) = 10.
Answer:
19 or 26
Step-by-step explanation:
You want the value of 3n² -8n -9, given that n(n -3) = 10.
Values of nWe recognize that 10 = 5·2 and that these factors differ by 3. This means n(n -3) = 10 is equivalent to saying n ∈ {-2, 5}.
Expression in nThe value of 3n² -8n -9 will be one of ...
(3n -8)n -9 = (3(-2) -8)(-2) -9 = (-14)(-2) -9 = 19 . . . . for n = -2
or
(3(5) -8)(5) -9 = (7)(5) -9 = 26 . . . . . . . for n = 5
The expression 3n² -8n -9 will be either 19 or 26.

23.A car travels 50+ miles in of an hour. What is the average speed, in miles per hour, of the car?
SHOW ALL WORK
Answer:
Step-by-step explanation:
Let's represent the number of people that Ms. Hernandez can bring to the zoo as "x". Each person will require an admission ticket, which costs $10.40 per person. Additionally, there is a parking fee of $3.
The total cost of admission tickets and parking is given as $150. We can set up the equation as follows:
10.40x + 3 = 150
To solve for x, we need to isolate the variable:
10.40x = 150 - 3
10.40x = 147
Now, divide both sides of the equation by 10.40 to solve for x:
x = 147 / 10.40
Using a calculator, we find:
x ≈ 14.13
Since we can't have a fractional number of people, we need to round down to the nearest whole number since we can't bring a fraction of a person. Therefore, Ms. Hernandez can bring 14 people to the zoo, including herself.
The average speed of a car is calculated by dividing the total distance traveled by the total time taken. In this case, the car travels 50+ miles in "of an hour".
To calculate the average speed in miles per hour, we need to determine the value of "of an hour". If the value is given as a fraction, we need to convert it to a decimal.
Assuming "of an hour" is 1/2 (0.5), the average speed can be calculated as:
Average speed = Total distance / Total time
Average speed = 50+ miles / (1/2) hour
To divide by a fraction, we can multiply by its reciprocal:
Average speed = 50+ miles * (2/1) hour
Average speed = 100+ miles per hour
Therefore, the average speed of the car is 100+ miles per hour.
Rotate the triangle 180 counterclockwise around the origin and enter the coordinates. Enter the number that belongs in the green box A (1,-1) B (4,-2) C (2,-4)
Answer:
A''(-1, 1), B''(-4, 2), C''(-2, 4)
Step-by-step explanation:
When rotated 180°, the symbol of the coordinames change
i.e., if x = 2 it becomes x = -2 and if y = -4, it becomes y = 4
so the coordinates A(1, -1), B(4, -2), C(2, -4)
change to A''(-1, 1), B''(-4, 2), C''(-2, 4)

Movimiento en linea recta
El movimiento en línea recta se refiere al desplazamiento de un objeto en una trayectoria rectilínea, es decir, sin cambios de dirección.
En este tipo de movimiento, la velocidad y la aceleración del objeto pueden variar, pero su dirección se mantiene constante a lo largo del recorrido.
El movimiento en línea recta puede ser uniforme o no uniforme. En el caso del movimiento uniforme, la velocidad del objeto es constante, lo que implica que el desplazamiento realizado en intervalos iguales de tiempo es también constante.
Por otro lado, en el movimiento no uniforme, la velocidad cambia a lo largo del tiempo, resultando en diferentes desplazamientos en intervalos de tiempo iguales.
La descripción matemática del movimiento en línea recta se basa en conceptos como la posición, la velocidad y la aceleración. La posición se refiere a la ubicación del objeto en relación a un punto de referencia, la velocidad representa la tasa de cambio de la posición y la aceleración indica la tasa de cambio de la velocidad.
El estudio del movimiento en línea recta es fundamental en la física y tiene aplicaciones en diversas áreas, como la mecánica, la cinemática, la dinámica y la física de partículas.
