What are the possible coordinates of point a?

well 0

Step-by-step explanation:

basically when a point lies on an axis,one of its coordinates must be zero,let's say point a-

if you look at how far the point is from the origin along the x-axis,the answer is zero,therefore the x-coordinate is zero,any point that lies on the y-axis has an x-coordinate of zero.

rounding to the nearest thousandth would be 452,000

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

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