The equation of circle c is (x-8)^2+(y+3)^2=49. find the center and radius of circle c.

a. c(-3,8)
r=7

b. c(-8,3)
r=7

c. c(8,-3)
r=7

d. c(8,-3)
r=49

answer: true

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
