General form of
(x-7)^2 + (y+3)^2 = 7^2

general form of
(x-9)^9 + (y+19)^2 = 9^2

I'm sure the answer is a

There should only be 1 solution

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
