Question

1. What is the equation of a circle with center (-5, 8) and radius 9?

Answer 1

Answer:

Your equation is:

(x−5)2+(y+8)2=92

Expanding from general form you can write this as:

x2−10x+y2+14y+−8=0

Step-by-step explanation:

i think its correct ig don't know sry but i tried hope it helps you ✨

Answer 2

Answer:

$(x+5)^2+(y-8)^2=81$

Step-by-step explanation:

General equation of a circle is $(x-a)^2+(y-b)^2=r^2$.

Center coordinates = (-5, 8)

a = -5           b = 8          r = 9

$\\(x+5)^2+(y-8)^2=9^2$

$(x+5)^2+(y-8)^2=81$
