How can the standard form of a linear function be used to model
real-world scenarios?
Answers
Let's look at an example.
-----------------------------------------
Problem:
At a high school play, tickets are sold at two different prices: student prices and parent prices. The student price is $2 while the parent prices is $3. On one night, 145 tickets were purchased and the total revenue was $335.
How many student tickets were purchased? How many parent tickets were purchased?
------------------------------------------
Solution:
Let x be the number of student tickets sold and y be the number of parent tickets sold.
We know that 145 people attended so x+y = 145 is the first equation we can set up. This equation is in standard form since standard form is Ax+By = C. Here we have A = 1, B = 1, C = 145.
The second equation we can form is 2x+3y = 335. This is also in standard form. This time we have A = 2, B = 3, C = 335.
The 2x is the amount of money made from just the students only. The 3y is from the parents only. The expression 2x+3y is the total from both groups. This total is set equal to 335 as this is the amount of money pulled in.
After forming both equations, we can write this system of equations
[tex]\begin{cases}x+y = 145\\2x+3y = 335\end{cases}[/tex]
To solve this system, we could isolate y in the first equation to get y = -x+145. Then plug this into the second equation to solve for x
2x+3y = 335
2x+3(-x+145) = 335
2x-3x+435 = 335
-x = 335-435
-x = -100
x = 100 .... number of student tickets bought
Use this to find y
y = -x+145
y = -100+145
y = 45 .... number of parent tickets bought
We can see that x+y = 100+45 = 145
And also 2x+3y = 2*100+3*45 = 200+135 = 335
These two facts help confirm we have the correct x,y values.

Ms. Aniston asked seven students in her class to collect pet food cans for a local animal shelter. The dot plot shows the number of food cans collected by each student. Each dot represents one student. What is the median of the data set? A. 9 B. 7 C. 6 D. 8
Answers
Step-by-step explanation: So for this problem it is important to know what a median is. The median is essentially the center number when everything is written out. So you want to take your line plot and write out each number on the bottom as many times as a dot appears above it. For this problem that would look like 6, 6, 7, 7, 8, 9, 9. Since you have seven numbers the center would be the 4th one. In ascending order out of these numbers the 7 occurs fourth thus giving you your answer.
Answer: answer is C 7

2nd condition: y = 2x + 1

Based on the 2nd and 3rd, we replace the 1st as following:

2x = 4 <=>
x = 2
Since x = 2, we solve the 2nd as following:

y = 4 + 1 <=>
y = 5

A box of cereal states that there are 75 calories in a three fourths 3/4-cup serving. What is the unit rate for calories per cup? How many calories are there in 2 cups of the cereal?
Answers
Answer:
a) The unit rate for calories per cup is 100 calories per cup
b) 200 calories in 2 cups of cereal.
Step-by-step explanation:
A box of cereal states that there are 75 calories in a three fourths 3/4-cup serving.
a) What is the unit rate for calories per cup?
This is calculated as:
3/4 cup = 75 calories
1 cup = x
Cross Multiply
3/4x = 75 calories × 1
x = 75 calories /3/4 cup
x = 75 ÷ 3/4
x = 75 × 4/3
x = 100 calories per cup
The unit rate for calories per cup is 100 calories per cup
b) How many calories are there in 2 cups of the cereal?
From the above question
3/4 cup = 75 calories
2 cups = x
Cross Multiply
3/4x = 75× 2
x = 150 ÷ 3/4
x = 150 × 4/3
x = 200 calories
There are 200 calories in 2 cups of cereal.

Answers
Complete question :
A man has a garden measuring 40m by 24m. He wants to divide it equally into the minimum number of square plots. what is the length of each square plot?
Answer:
8 m
Step-by-step explanation:
Given that :
Dimension of garden = 40m by 24m
Length of garden = 40m
Width of garden = 24m
To Obtain the length of each square plot if the garden is divided into minimum number of square plots ; we take the highest common factor of the dimension:
Length (40) = 1, 2, 4, 5, 8, 10, 20, 40
Width (24) = 1, 2, 3, 4, 6, 8, 12, 24
The highest common factor here is 8 ;
Thus, the length of each square plot is 8m

how many times does 8 go into 70
Answers
Hope this helps
Ty
8 goes into 70 exactly 8 times, with a remainder of 6.
When dividing 70 by 8, we follow these steps:
Divide the first digit of the dividend (7) by the divisor (8). In this case, 7 divided by 8 is 0 with a remainder of 7.
Bring down the next digit of the dividend (0) and divide it by the divisor (8). 0 divided by 8 is 0.
Since there are no more digits in the dividend, the division process is complete.
The quotient is the result of the division, which is 8. The remainder is the value left over after division, which is 6 in this case.
Therefore, 8 goes into 70 exactly 8 times, with a remainder of 6.

What is the slope of the line that passes through the points (9,4) and (9, -5)? Write your answer in simplest form.
Answers
Answer:
The slope of the line is undefined, and the equation of the line is x = 9.
Step-by-step explanation:
Given the points
(9, 4)(9, -5)Finding the slope between (9, 4) and (9, -5)
It is clear that the value of x = 9 is the same in both points.
It means no matter what the value of y is, the value of x remains the same.
It means the line is vertical.
Therefore, the slope of the vertical line is undefined, because the value of x is not changing.
Thus, the slope of the line is undefined, and the equation of the line is x = 9.

cost = flat fee + books * cost per book
133 = 5 +b*8 where b is the number of books
133 = 5+8b

I got three answers for alot points ok this is the first question what is : 1/2 + 3/6 =
next question: 1/3 - 1/4 =
last question: 5 2/3 - 2 1/2
Answers
Answer:
1. 1
2. 1/12
3. 3 1/6
Step-by-step explanation:
Solution for #1. First, you have to get a common denominator. Here, that would be 6. In order to give 1/2 a denominator of 6, you will need to multiply the numerator and the denominator by 3. That will give you 3/6. Add that to the other 3/6 (3/6+3/6) which equals 6/6 which can be simplified to 1.
Solution for #2. This is just like #1. First, you have to get a common denominator. Here, that would be 12. In order to give 1/3 a denominator of 12, you will need to multiply the numerator and the denominator by 4. That will give you 4/12. Then, to give 1/4 a denominator of 12, you will need to multiply the numerator and the denominator by 3. That will give you 3/12. Then, subtract (4/12-3/12). You will get an answer of 1/12.
Solution for #3. This is slightly different from the others, I has two more steps. First, you need to changed the mixed fractions into improper fractions. You will get 17/3 and 5/2. Then, you have to get a common denominator. Here, that would be 6. In order to give 17/3 a denominator of 6, you will need to multiply the numerator and the denominator by 2. That will give you 34/6. Then, to give 5/2 a denominator of 6, you will need to multiply the numerator and the denominator by 3. That will give you 15/6. After that, subtract (34/6-15/6). You should get 19/6. Finally, divide 19/6 and you should get 3R1. So, the mixed fraction version of 19/6 is 3 1/6 (I did this by using the 3 from 3R1 as the whole number and I just put the remainder of 1 over 6 as the fractional part). You can multiply to check your answer.
