What is the center of the circle given by the

equation (x + 17) 2 + (y - 4) 2 = 23?

A. (-4, 17)

B. (-17, 4)

C. (17, - 4)

D. (4, - 17)

B. (-17, 4)

Step-by-step explanation:

We can write the equation of a circle in the form

(x-h) ^2 + (y-k) ^2 = r^2 where (h, k) is the center and r is the radius

(x + 17) ^2 + (y - 4) ^2 = 23

(x - - 17) ^2 + (y - 4) ^2 = (sqrt (23)) ^2

The center is (-17,4) and the radius is (sqrt (23)
