Asap! will give brainlist! a. y = 7 b. y = 32 c. y cannot be determined with the information given d. y = 4

If you know that the triangles are congruent then you can use CPCTC to show that 21=3x and 60=4x+8y

We can easily divide 21 by 3 which gives us x=7 so we can multiply 4 times 7 and then subtract that from 60 which gives us 32=8y and then when you solve from there you get y=4

"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.
