Which of the following is a rational number? (4 points)
197, 198, 199, V100

I believe the answer would be the last option but idk if the v was a typo or not.

Step-by-step explanation:

to find a rational number you put the number in a calculator and square root it.

"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.
