Step-by-step explanation:
Step 1: Define Equation
6v + 18 - 9v = -12
Step 2: Solve for v
Combine like terms: -3v + 18 = -12Isolate v term: -3v = -30Isolate v: v = 10Step 3: Check
Plug in v into the original equation to verify it's a solution.
Substitute in v: 6(10) + 18 - 9(10) = -12Multiply: 60 + 18 - 90 = -12Add: 78 - 90 = -12Subtract: -12 = -12Here we see that -12 does indeed equal -12.
∴ v = 10 is the solution to the equation.
What is an equation of the line that passes through the points (-6, -7) and
(6,3)? Put your answer in fully reduced form.
Answer: y = 5/6x - 2
Step-by-step explanation:
Y =mx + b
Step 1 find slope also known as m:
Y2 - y1 / x2 - x1
3-(-7)/6-(-6) = 10/12 can be reduced to 5/6
Step 2 find b:
3 = 5/6 (6) + b
3 = 30/6 + b
3 = 5 + b
-5 - 5
-2 = b
Step 3 write equation:
Y = 5/6x - 2
The probability that event A occurs is 0.4, and the probability that events A and B both occur is 0.25. If the probability that either event A or event B occurs is 0.6, what is the probability that event B will occur
Answer:
The probability that event B will occur is 0.45
Step-by-step explanation:
Given;
probability that event A occurs, P(A) = 0.4
the probability that events A and B both occur, P(A ∩ B) = 0.25
the probability that either event A or event B occurs, P(A ∪ B) = 0.6
To determine the probability that event B will occur, we use probability addition rule;
P(A) + P(B) = P(A ∩ B) + P(A ∪ B)
0.4 + P(B) = 0.25 + 0.6
0.4 + P(B) = 0.85
P(B) = 0.85 - 0.4
P(B) = 0.45
Therefore, the probability that event B will occur is 0.45
What is the slope of the line NP
Answer:
The slope of NP is [tex]\frac{-5}{7}[/tex] ⇒ B
Step-by-step explanation:
In any square, every two opposite sides are parallel and every two consecutive sides are perpendicularParallel lines have the same slopeThe product of the slopes of the perpendicular lines is -1, which means if the slope of one m, then the slope of the other is [tex]\frac{-1}{m}[/tex] (reciprocal m and change its sign)The rule of the slope of the line which passes through the points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]In square MNPR
∵ MN and NP are adjacent sides
∴ MN ⊥ NP
∵ M = (3, 8) and N = (-2, 1)
∴ x1 = 3 and y1 = 8
∴ x2 = -2 and y2 = 1
→ Use the rule of the slope above to find the slope of MN
∴ m(MN) = [tex]\frac{1-8}{-2-3}[/tex]
∴ m(MN) = [tex]\frac{-7}{-5}[/tex]
∴ m(MN) = [tex]\frac{7}{5}[/tex]
∵ MN ⊥ NP
∴ The product of their slopes = -1
→ Reciprocal the slope of MN and change its sign
∴ m(NP) = [tex]\frac{-5}{7}[/tex]
∴ The slope of NP is [tex]\frac{-5}{7}[/tex]

Answer:
n = 4752 gallons
Step-by-step explanation:
Given
Dilivery: 396 dozen gallon in a day
RequirEd
determine the number of the gallon in a day
we understand that:
n= 396 dozen
unit conversion
1 dozen = 12
so
n = 396 dozen gallon
n = 396× 12
n = 4752 gallons
hence 4752 gallons milk is delivered daily

Between 9 p.m and 6:45 a.m, the water level in a swimming pool decreased by 3/16 in. Assuming that the water level decreased at a constant rate, how much did the water level drop each hour?
Answer:
9:00 pm to 6:45 am = 9 hours 45 minutes = 9.75 hours
Water level drops 3/16" (or .1875") every 9.75 hours
.1875 / 9.75 = 0.0192307692 inches per hour

Lillian thinks that 725 - 4x3 is the same as 3.22. Which statement shows that it is
NOT the same?
Answer:
The correct option is (c).
Step-by-step explanation:
Lillian thinks that 7x⁵ - 4x³ is the same as 3x².
Option (a) :
7x⁵ - 4x³ = 3x²
It is wrong, as we cannot say directly that they are equal.
Option (b):
7x⁵ - 4x³ ≠ 3x²
It is wrong, as we cannot say directly that they are not equal.
Option (c):
7(2)⁵ - 4(2)³ = 3(2)²
LHS,
7(32) -4(8) = 192
RHS, 12
Here, LHS ≠ RHS
It is correct.
Option (d) :
7(2)⁵ × 4(2)³ = 3(2)²
Here, multiplication is done instead of addition. So, it is wrong.
Hence, the correct option is (c).

Step-by-step explanation:
Where is the midline of this function?
Answer:
the midline is the line:
y = 0.
Step-by-step explanation:
The midline of a function is a horizontal line that divides evenly the graph of the function in two parts.
Particularly, for trigonometric functions, we usually have:
f(x) = A*sin(k*x + p) + M
Where:
A is the amplitude.
x is the variable
k is a constant related to the frequency of the function.
p is a phase shift
M is the midline of the function, which means that the line that divides evenly the graph is y = M.
For our case, we have:
y = f(x) = 3*sin(2*x - π)
Then:
A = 3
k = 2
p = -π
And we do not have a constant term in that equation, this means that:
M = 0
This means that the line that divides evenly the graph is the line y = 0.
what number makes this equation true.

19 2/5
8
7 2/5
24 4/5
Answer:
The answer is 7.4
Step-by-step explanation: I don’t really know a better way to tell you the explanation than just tell you the answer
The simplified expression is 7 3/5 or 7.6.
To simplify the expression using the order of operations (also known as PEMDAS), follow these steps:
Step 1: Simplify within parentheses (if any).
There are no parentheses in the expression, so we move to the next step.
Step 2: Perform multiplications and divisions from left to right.
First, let's divide 15 by 5:
15 ÷ 5 = 3
Step 3: Perform additions and subtractions from left to right.
Now, let's add 4 3/5 and 3:
4 3/5 + 3
To add the whole numbers, 4 and 3, we get 7.
To add the fractions, we need a common denominator. The common denominator of 5 and 1 is 5. Converting both fractions to have a denominator of 5:
4 3/5 + 3 = 4 3/5 + 15/5
Now, we can add the fractions:
4 3/5 + 15/5 = (4*5 + 3 + 15) / 5
= (20 + 3 + 15) / 5
= 38/5
Step 4: Express the result in mixed number form (if necessary).
38/5 can be expressed as a mixed number by dividing the numerator (38) by the denominator (5). The quotient is the whole number, and the remainder is the numerator of the fraction:
38 ÷ 5 = 7 with a remainder of 3
Therefore, the simplified expression is 7 3/5, which is equivalent to 7.6 as a decimal.

Step-by-step explanation:
GOT IT RIGHT ON KHAN and
150,000 divided by 5 so 30,000 then 30,000 divided by 15
Each video gets an average of 1,500,000 views.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
Each video gets an average of 1,500,000 views
Video get Views = 3 x 1,500,000
= 4,500,000 Views
Total Views = 90,000,000 Views
Number of months = Total Views/Views per month
Number of months = 90,000,000 / 4,500,000
= 20 Months
Hence, For 20 Months Dagogo need to upload videos to get 90,000,000 views on his channel.

if 4 is the constant of proportionality is this equation correct? y = 4x + 2
Answer:
4 is not the constant. 2 is.
Step-by-step explanation:
In the following equation: y = 4x + 2
x and y are variables. x can be any given number, and y would be the resulting answer.
4 is not the constant, because the product it will produce varies on what x will be.
2 is a constant, because it will not change regardless what is put into x. It will continue to stay as 2.

Step-by-step explanation:
Step 1: Define
3n - 8 = 32 - n
