You and your friend collect 90 cans. Your friend collects 50 cans. Let c be the number of cans you collect. Write an equation you can use to find c.

I think C + 50 = 90

C = 90 - 50 = 40

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)
