Identify the equation of the circle that has its

Option C

Step-by-step explanation:

Standard equation:

r^2 = (x-h)^2 + (y-k)^2

Radius: r

Center: (h,k)

Plug the values in.

r^2 = (x+8)^2 + (y-15)^2

Using distance formula, you conclude that the radius is 17 since the distance from (-8,15) to (0,0) is 17.

r^2 = 289

That means option C is the right answer.

289 = (x+8)^2 + (y-15)^2

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
