Question

What is the center of the circle given by the equation (x + 5)2 + (y - 8)2 = 1?

Answer 1

Do you know the standard formula for a circle? HINT: What do h and k have to do with it?

Answer 2

2x+10+2y-16=1
Thats all i got

Answer 3

A. (-5, -8)
B. (5, -8)
C. (5, 8)
D. (-5, 8)

Answer 4

Those 2s are exponents you don't have to use.

\[(x-h)^{2} + (y-k)^{2} = r ^{2}\]

is the standard form. the h and k are the coordinates of the center (h,k), however; because of the way this formula is written you have to think of h and k as what would make their parentheses = 0.

Answer 5

D

Answer 6
