Rachelle and Aileen are both working on their music collections. By the end of the first month, Rachelle has collected 21 albums and the number of cumulative
albums that she has increases by 20% each month. Aileen has 28 albums by the
end of the first month and she buys 3 new albums every month. What is the first
month in which Rachelle will have more albums than Aileen? *

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

congruent! because each point is being moved the same distance.

8y^50

step-by-step explanation:
