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

Step-by-step explanation:

(x+6)2+(y+4)2=36

2x+12+2y+8=36

2x+2y+12+8=36

2(x+y)+20=36

2(x+y)=36-20

2(x+y)=16

x+y =16/2

x+y=8
