Suppose that angle LAP and LAR are adjacent angles, m angle LAP=3x+7, m angle LAR= 4(x-4), and m angle PAR=2(3x+7). Part A: what can you conclude about line AL? Part B: Is the perpendicular bisector of a line segment also and angle bisector?

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

"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.
