A circle is represented by the equation below: (x − 5)2 + (y + 7)2 = 49 Which statement is true? The circle is centered at (−5, 7) and has a radius of 7. The circle is centered at (5, −7) and has a diameter of 7. The circle is centered at (5, −7) and has a radius of 7. The circle is centered at (−5, 7) and has a diameter of 7.

C

Step-by-step explanation:

The circle is given by the equation:

The standard form of a circle is:

Where (h, k) is the center and r is the radius.

We can rewrite our equation as:

So, the center (h, k) is (5, -7) and the radius is 7.

Hence, our answer is C.
