The "10" should be a "10x" and the "=5" should be an "= -5", right?thetomps said:x^2 + y^2 + 10x - 8y + 5 = 0
x^2 + 10 + y^2 - 8y = 5
Given (x - h)<sup>2</sup> + (y - k)<sup>2</sup> = r<sup>2</sup>, the center is at (h, k), not (-h, -k), and the radius is r, not... I don't know how you got "6" from "sqrt[46]"...?thetomps said:(x+5)^2 + (y-4) = 46
center (5,-4) radius 6 ???
No; the center is at (h, k), not (-h, k).thetomps said:opps sorry so would it be center (5, 4)
I don't know how you got sqrt[46] equalling 7. Don't you?thetomps said:radius 7 how do I find this radius?
