Question

What is the center and radius of the circle with equation x2 + y2 – 8x – 6y – 75 = 0?

Answer 1

you gotta complete the square on x and y

Answer 2

Oh ok I got you ty

Answer 3

Would it be (4,3) ?

Answer 4

xJai, how did you obtain (4,3) ? Like, what specific steps did you go through...

Answer 5

Combining the like terms halfing then squaring the terms with the x then rationalizing them then once rationalized you would make them equal 0

Answer 6

(4,3) is correct, and it sounds like you know how to complete the square. cheers. :)

Answer 7

do you know how to find the radius xjai?

Answer 8

(x-4)^2 -16 + (y-3)^2 - 9 = 75
(x-4(^2 + (y-3)^2 = 100
so radius is 10

Answer 9

center (4,3) and radius 10
