The equation of a circle is (x+9)2+(y+6)2=225 . what is the center of the circle? enter your answer in the boxes. ( , )

Step-by-step explanation:

We have been given an equation of a circle . We are asked to find the coordinates of the center of the given circle.

We know that center-radius form of a circle is in format: , where,

,

Upon comparing our given equation with center-radius form of a circle we will get,

Therefore, the center of our given circle is at point .

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
