- in the second line bc. the second equation we need multiplie just by 3 and ot by 5
- so there above was multiplied by 5 and so than 5*(-5y) not equal -15y so this is equal -25y

Depends how long each call is.
80 people divided by 4 phones is 20 rotataions on the phone.
If each call is 2 minutes that’s 20x2 = 40 minutes.

Step-by-step explanation:
Answer: Y and Y'' are congruent after the translation, but not after the dilation.
Step-by-step explanation:
We know that we generally prefer rigid transformations if want to create congruent images.
There are three basic kinds of rigid transformations:
1) rotation 2) reflection 3) translation
So, they all create congruent images.
But a dilation does not create congruent images because it creates an image of similar same shape as the original but not the same size.
Given : Triangle XYZ is translated and then dilated by a scale factor of 4 centered at the origin.
Then, the correct option is "Y and Y'' are congruent after the translation, but not after the dilation."
