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

Yes, your answer is correct. The equation (x + 5) + (y + 3) = 169 represents the position and range of the source of a radio signal. To understand the position and range, we need to analyze the equation.
The equation is in the standard form of a circle, (x - h)^2 + (y - k)^2 = r^2, where (h, k) represents the center of the circle and r represents the radius.
In this case, we can rewrite the equation as (x - (-5))^2 + (y - (-3))^2 = 169, which matches the standard form. Therefore, the center of the circle is at the coordinates (-5, -3).
To find the radius, we need to take the square root of the value on the right side of the equation. In this case, the radius is √169, which equals 13.
So, the position of the source is at the center of the circle, (-5, -3), and the range of the signals extends 13 units in all directions from the center.
Therefore, you're correct that the center of the source is located at (5, 3) and the range of the signals is 13 units.
