Input a number that has a 5 with 1/10 of the value of the 5 in 105,234

I'm pretty 500 or 102,534 both work.

The 5 just has to be in one digit less

"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.
