Answer:
M is (-5,6)
N is (1,0)
P is (-4,2)
Step-by-step explanation:
We have to move all our coordinates in the same position and distance so we add and subtract the x and y values
M (-6,1) we add 1 to the x value and add 5 to the y value
M (-6+1,1+5)
So M prime is (-5,6 and we do that for the rest

Taylor makes $13 per hour at the grocery store. she always works between 10-15 hours per week to leave time for her homework and band practice. her gross wages can be modeled as w(h) = 13h, where h is the number of hours worked per week.
1. how much will her gross wages be if she works 12 hours this week?
2. what is the domain of this function?
3. what is the range of this function?
Answers
a) Her gross pay will be $156
b) The domain is D: [10, 15]
c) The range is R: [$130, $195]
What will be her gross wage if she works 12 hours this week?
We know that Taylor earns 13 dollars per hour on her job at the grocery store.
Then, if she works x hours in the week, her gross wage will be given by the linear equation:
g(x) = $13*x
So, if she works 12 hours, her gross pay will be:
g(12) = $13*12 = $156
what is the domain of this function?
we know that she works between 10 and 15 hours peer week, so the domain (set of the possible inputs of the function) is:
10 ≤ x ≤ 15 or [10, 15] in interval notation.
what is the range of this function?The range is the set of the outputs, the minimum of the rane is:
g(10) = $13*10 = $130
The maximum of the range is:
g(15) = $13*15 = $195
The range of the linear function is: [$130, $195]

What is -33.44/-1.9 in division?
Answers
The division of the number -33.44/-1.9 is 17.6.
What is referred as division?Division is one of four fundamental mathematical operations, along with addition, subtraction, as well as multiplication.
Division is defined as the separating of a large group in to other smaller groups so that each group has an equal amount of items.Division is a process of repeated subtraction. It is the inverse operation of multiplication.It is characterized by the creation of equal groups. When we divide numbers, we break them down into smaller numbers so that the multiplication of the those smaller numbers equals the larger number taken.For the given expression;
= -33.44/-1.9
as, both numerator and denominator is negative values, both negative signs will be cancelled.
Now, divide numerator 33.44 by denominator by 1.9, we get 17.6.
Thus, the division of the number -33.44/-1.9 gives quotient 17.6.

A sample in a 1-cm cuvette is assessed with a spectrophotometer set to 620 nm. If the sample returns a transmittance of 62%, then what is the approximate absorbance of the sample?.
Answers
The absorbance of the given sample is 0.2076.
Length of the cuvette = 1 cm
Wavelength of the spectrophotometer = 620nm
Transmittance of the sample = 62%
We know, absorbance is related to transmittance by the formula written below;
A = log(1/T) equation 1
Also, percent transmittance %T = 100T
or we can write, T = (%T) / 100
On substituting value of T in equation 1 , we get
A = log(100/(%T))
⇒ A = log(100) - log (%T)
⇒ A = log([tex]10^{2}[/tex]) - log(%T)
⇒ A= 2log(10) - log(%T)
We know, log10 = 1. On substituting the value of log 10 in above equation, we get
A = 2 - log(%T)
⇒ A = 2 - log(62)
⇒ A = 2 - 1.7924
⇒ A = 0.2076
The absorbance of the given sample is 0.2076.

Answers
The number that fits in the given situation is -20.
What exactly are equations?An equation, in its most basic form, is a mathematical statement that shows that multiple mathematical expressions are equal.For example, 3x + 5 = 14 is an equation in which 3x + 5 and 14 are two expressions detached by a 'equal' sign.Now,
Let us suppose the number is x.
The sum of the same number and ten will be written as x + 10.As a result, the next condition is twice the sum, which can be written as:
2 × (x + 10)As a result of the condition, we can write the equation as:
x= 2 × ( x + 10 ) or 2x + 20 = xSolve for x: x = 2x + 20
2x + 20 = xTaking 20 off both sides:
2x + 20 - 20 = x - 20 2x = x- 20 2x - x = -20 x = -20Therefore, the number that fits in the given situation is -20.

The answer is k⁴n⁶/3 after solving the expression.
Given, the expression is kn/3k⁻³n⁻⁵
now we must simplify the expression with the help of the negative exponent rule.
A base that is on the fraction line's denominator side can be indicated by a negative exponent. In other words, according to the negative exponent rule, a number with a negative exponent should be added to the numerator and vice versa.
that is, a⁻ⁿ = 1/aⁿ
therefore, kn/3k⁻³n⁻⁵ = knk³n⁵/3

Makayla is taking a math course and is working with the perimeter of rectangles. She knows the perimeter and length of her rectangle but wants to solve for the width. Rearrange the following equation for W, where P is the perimeter, L is the length, and W is the width of the rectangle.
P = 2L + 2W
Answers
Step by step
- Subtract 2L from both sides of the equation to isolate W
P = 2L -2L + 2W
P -2L = 2W
- Divide both sides of the equation by 2 to solve for W
P-2L/2 = 2/2 W
P - 2L /2 = W

The cost of labor per hour is $45.
The total cost of the parts is $141.The total time for which the technician worked is 4.25 hours.The total cost of repair is $332.25.Let the cost of labor per hour be "x".The total cost of labor is the product of the total time for which the technician worked and the cost of labor per hour.The cost of labor is 4.25*x.The total cost of repairing the computer is the sum of the cost of the parts and the cost of labor.The total cost of repairing the computer is $141 + 4.25*x.The equation is as follows:332.25 = 141 + 4.25*x191.25 = 4.25xx = 191.25/4.25x = 45Thus, the cost of labor per hour is $45.To learn more about equation, visit :

It has no one moving in and an average of 200 people moving away every month. In about how many months will the populations of the towns be equal? Write an equation to model the situation. Then solve the equation and answer the question.
Answers
It would take 10 months to equate the population of both the towns
Let the number of months required to equate the population of both the town( Town A and Town B) be x
This question can be solved using linear equations
So, town A's population would be current population adjusted with migration of people which is 42975-125x+150x
And town B's population would be current population adjusted with migration of people which is 45225 -200x
As at the end of x months the population of the two towns is equal, so equating both the linear equations
42975 -125x +150x = 45225-200x
Now solving the equation for x
150x-125x+200x= 45225-42975
225x=2250
Therefore x= 2250/225= 10
Hence it would take 10 months to equate the population of both the towns
