The rule is:

So, we have:


Translate circle C' 7 units right;
The rule is:

So, we have:


<em>At this point, both circles now have the same center at (4,9)</em>
The next step is to dilate circle E by 4/3
This will only affect radius and not the center of E
The rule is:



So, we have:
-- equal radii
--- equal center
