Question

give the radius and center for the following equation.

(x + 5)2 + (y + 8)2 = 16

Answer 1

(x – h)^2+ (y – k)^2 = r^2

does that help?

Answer 2

. no not really.

Answer 3

Center at (h, k)

Answer 4

(x – h)^2+ (y – k)^2 = r^2
(x + 5)^2 + (y + 8)^2 = 4^2

Answer 5

this is what i did
(x^2+10x+25)+(y^2+16y+64)

Answer 6

you got it simplified

(x – h)^2 + (y – k)^2 = r^2
(x - -5)^2 + (y - -8)^2 = 4^2

r is the radius
(h, k) is the center

Answer 7

so what am i suppose to do next?

Answer 8

ooooh nm i got it! :D thanks @surdawi

Answer 9

what did you get?

Answer 10

-5,-8 and 4

Answer 11

nope
center should be written as a point (-5,-8)
and r = 4;

Answer 12

thats what i mean.
