An electrician has a spool of wire that is 200 m long. she needs four pieces of wire measuring 42.3 m, 37.8 m, 55.6 m, and 35.7 m. about how much wire will be left on the spool after she finishes her job? give your answer with the appropriate precision.

"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.
