Please write that x^2 + y^2 = 7^2.  The " ^ " indicates exponentiation.
This is the equation of a circle with center at the origin and radius 7.

Supposing that you translate this circle's center to point (h,k).  The equation is then 
            (x-h)^2 + (y-k)^2 = 7^2.  The new center is (h,k) = (-3, 2).  Substitute -3 for h and 2 for k in the above equation.

Simplify your result and you'll then be done!

Someone help me please
vladimir1956 [14]

Step-by-step explanation:

Hi,

You will have to move the pre-image 15 units to the right. You're also going to have to flip the image horizontally (kind of like flipping it across the x-axis) and after that, you're going to have to flip it so that it's facing the left side.

1) 15 units right

2) Flip-up

3) Flip to the left

Hope this helps :)
