Question

A circle is defined by the following equation:
-2x^(2)-2y^(2)+24x-54=0
What are the coordinates ofits center?

Answer 1

(6,0)

Answer 2

HEY CHIZZ whats d ans

Answer 3

^what?

Answer 4

first rewrite the equations as
\[2x^2+2y^2-24x-54=0\]
divide by 2
\[x^2+y^2-12x-27=0\]
complete the square:
\[(x-6)^2+y^2=27=36=63\]
center is (6,0) radius is \[\sqrt{63}\]

Answer 5

typo. 27+36 = 63

Answer 6

another mistake. should be +54 not -54 so right hand side is -27+ 36 = 9 and radius is 3. sorry

Answer 7

so is the center still (6,0)?
