Find the center of the circle whose equation is x2 - 10x + y2 - 10y = -1.

the center of the circle are (5,5)

Step-by-step explanation:

x^2 - 10x + y^2 - 10y = -1.

x^2 - 10x + (-5)^2 + y^2 - 10y + (-5)^2 = -1 +  (-5)^2 +  (-5)^2

(x-5)^2 + (y-5)^2 = -1 +25 + 25

(x-5)^2 + (y-5)^2 = 49

the center of the circle are (5,5)

To answer the question, the first thing we must do is rewrite the following expression:

4 times as many as 25

We rewrite this expression in algebraic form.

We have then:

4 times as many as 25 = 4 * 25

Making the corresponding calculation, we will obtain:

100 is 4 times as many as 25
