Please help me with this question

Answer 1

The equation of a circle is:

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

where center is (h,k) and radius is r. Therefore, in this question, you need to check if the (h,k) values are the same. Let's view each option and judge accordingly:

A. (0,-4) and (-4,0) : Nope
B (-3,3) and (3,-3) : Nope
C. (7,2) and (-7,-2) : Nope
D. (2,5) and (2,5): Yes, the centers are equal.

Therefore, your answer is option D.
