Question

The equation (x + 6)2 + (y + 4)2 = 36 models the position and range of the source of a radio signal. Describe the position of the source and the range of the signals

Answer 1

This is the equation of a circle:
(x-h)² + (y-k)² = r²

(h, k) is the center of the circle, and r is the radius of the circle.

Answer 2

I think your source is (-6,-4) and your range is 6
