5 108
10 88
15 68
a. Write an equation that represents the amount of cleaner in the tank after x minutes.
y = - Ix + 128
b. How much cleaner is in the tank when the cleaning begins?
There are
fluid Ounces of cleaner in the tank.
C. After how many minutes is the tank empty?

answer: b

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
