Step-by-step explanation:
Correct me if i'm wrong.
But it seems to make sense with my calculations....
If the center is (0, 0), then there is no side to side or up or down motion. The center is at the origin. The standard form of a circle is (x-h)^2 + (y-k)^2 = r^2. Your h and your k are both 0's, so just fill in and square the radius:
x^2 + y^2 = 64
8x+15=7
answer: x= 1 hope this help
