Estimate the following sum by rounding each number to the nearest ten.
129.5 + 34.62 + 19.1

If your using Odyssey-ware the answer is 180 like he said 4 below let it go 5 and above round up it. Obviously wanted on my program to round down from 184 therefor the answer is 180.

"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.
