The equation of a circle is written as (x-h)^2 +(y-k)^2 = r^2
h is the x value of the center and k is the y value of the center and r is the radius.
Replace h, k and r with the given information:
(x- -7)^2 + (y - -6)^2 = 4^2
Simplify:
(x+7)^2 + (y+6)^2 = 16
The intersection of the two equations is (1, 1/5). Since the question is asking for the value of x, x = 1.
I'm pretty sure that it would be 1,000...
Addition will be the last operation
