Which of the following is the equation of a circle with center (a, −b) and radius r? (x+a)2+(y−b)2=r2

(x−a)2+(y+b)2=r2

(x−a)2+(y+b)2=r

(x+a)2+(y−b)2=r

250

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
