Answers
w - width
2w - length
60 - perimeter
w + w + 2w + 2w = 6w - perimeter
The equation:
6w = 60 divide both sides by 6
w = 10 → 2w = 2 · 10 = 20
The area: A = width × length
A = (10)(20) = 200
Answer: The area of the garden is equal 200 square units.

Part B: Which company would charge less for cleaning 8 windows? Justify your answer. (3 points)
Part C: How much money is saved by using the services of Company B instead of Company A to clean 6 windows? (3 points)
Answers
y=6x+12
y=5x+15
x is the amount of windows, y is the total amount of money
Part B
y=6(8)+12 =60
y=5(8)+15 =52
Company B
Part C
y=6(6)+12 =48
y=5(6)+12 =42

On the attached diagram you can see all graphs of functions b(x), d(x), m(x) and p(x).
Finding the inverse of a function f(x):
1. First, replace f(x) with y. This is done to make the rest of the process easier.
2. Replace every x with a y and replace every y with an x.
3. Solve the equation from Step 2 for y. This is the step where mistakes are most often made so be careful with this step.
4. Replace y with In other words, you’ve managed to find the inverse.
5. Remember: the domain of f is the range of and the range of f is the domain of
.
Using this algorithm, you can find the inverse only in case C:
for m(x)=-7x:
1. y=-7x.
2. x=-7y.
3. y=-x/7.
4. .
5. The domain and the range of m(x) are all real numbers as well as the domain and the range of
Functions b(x) and p(x) are not one-to-one functions (see attached diagram), then you can't find an inverse function. Function d(x) doesn't include x, then you can't also find an inverse function.
Answer C
y=-7x ==>x=-7y==>y=-x/7 is the inverse of m(x)
