Afootball team gained 5 yards and then last 7 yards. what real number represents the teams position relative to its original position

Step-by-step explanation:

Think of this situation as a number line in which the team starts at 0 yd.

Gaining yards is the positive direction and losing yards is negative.

Start at 0 yd and go 5 yd to the right. You are at +5.

Then go 7 yd left. You end up at -2.

+5 – 7 = -2

47 - 90 = 43

43 - 180 = x

x = 137

"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.
