B. Directions: Fill in the blanks to determine the center and radius given the equation of the circle. A) x2 + y2 + 4y = 20
x2 + (y2 + 4y +
-= 20 + 4
x2 + (y + -)=
c C( _ _), r=
B)
x2 + y2 - 6x = 40
x2 - 6x + ___+ y2 = 40 + (-)
(x-_)2 + y2 =
cl_), r= -
, _
C
x2 + y2 - 10x + 14y - 24 = 0
(x² - 6x+ - + (y²+2y+ ) = 24 +
(x-_)+ (y + __)?
cl) = -
