Question

The equation below describes a circle. what are the coordinates of the center of the circle?

(x+5squared)+(y+2squared)=21 squared

Answer 1

(-5,-2)

Explanation:

the equation involved is a circle let us clearly write the equation first:

From the standard equation of the circle:

So from the equation given above, our x would be -5, and our y is equivalent to -2.

So the center of our circle is located at the point (-5,-2)

Answer 2

Since, the equation involved is a circle let us clearly write the equation first:

`(x+5)^2+(y+2)^2=21^2`

From the standard equation of the circle:

`(x-h)^2+(y-k)^2=r^2`

`(h,k)=(x,y)`

So from the equation given above, our x would be -5, and our y is equivalent to -2.
So the center of our circle is located at the point (-5,-2)
