Question

(x – 4)2 + (y – 2)2 = 25
how do i solve this step by step?

Answer 1

2x-8+2y-4=25

Answer 2

2x+2y=37

Answer 3

x+y=37/2

Answer 4

y=37/2-x

Answer 5

(x – 4)2 + (y – 2)2 = 25
solve for x
(x – 4)2 =- (y – 2)2 + 25
(x – 4)2 =25- (y – 2)2
now sqrt of both
|x-4|=sqrt(25- (y – 2)2 )
x-4=+-sqrt(25- (y – 2)2 )
x=4+-sqrt(25- (y – 2)2 )

like that for y
