Parallelogram ABCD is a rectangle. AC = 6y − 1
BD = 4y + 13

What is AC?

Sorry to the last person who answered on that other question I pasted the wrong one
Just making sure my answers are right!

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

i believe it's a.

i'm not sure on this one, most likely correct.
