Which equation describes the circle

deff fn [24]

Answer:

B. (x-5)²+(y+1)² = 49

Step-by-step explanation:

An equation of a circle with center (h, k) and radius r is

$\large \boxed{ {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} }$

We have all given information we need. Our h is 5 - Our k is -1 and our radius is 7

Substitute these values in

$\large{ {(x - 5)}^{2} + {(y - ( - 1))}^{2} = {7}^{2} } \\ \large{ {(x - 5)}^{2} + {(y + 1)}^{2} = {7}^{2} } \\ \large{ {(x - 5)}^{2} + {(y + 1)}^{2} = 49 }$

So the answer is B choice.
