The equation (x + 5) + (y + 3) = 169 models the position and range of the source of a radio signal. Describe the position of the source and the range of the signals.

Question

???? Would the answer be (5,3) is the center and 13 is the range of signals..??

Answer 1

did you mean (x+5)^2 + (y+3)^2 = 169 ?

then the centre would be (-5,-3) and the radius , (or the range) , would be 13
