The equation of a circle is (x+7)to the second power+(y−13)to the second power=196 .What is the center of the circle?Enter your answer in the boxes.
Accepted Solution
A:
Instead of writing "(x+7) to the second power", you can write "(x+7)^2" which is more efficient.
The equation given to us is (x+7)^2 + (y-13)^2 = 196 which is the same as (x-(-7))^2 + (y-13)^2 = 14^2 and that equation is in the form (x-h)^2 + (y-k)^2 = r^2
