Best ResponseYou've already chosen the best response.0\[(x3)^2+(y+4)^2=9\] if center = (h,k) and radius = r, then the general form is \[(xh)^2+(yk)^2=r^2\] Thus center=(3,4) and r=3

Best ResponseYou've already chosen the best response.0why is 4 negative and 3 positive and thank so much

Best ResponseYou've already chosen the best response.0because it must be in the form (xh)^2 and so for (xh) to equal (x3), h must be positive 3. Similarly, if (y+4)=(yk), then k=4

Best ResponseYou've already chosen the best response.0ok how is this supose to be graphed because im looking at the example of the graph and it very difficult

Best ResponseYou've already chosen the best response.0well, it's going to be a circle, so I would, starting from (3,4), go 3 units up, down, left and right.

Best ResponseYou've already chosen the best response.0ok, this one is actually a little simpler. See, to get it in the standard form, all we do is rewrite it as \[(x0)^2+(y0)^2=6^2\] now clearly it's the same equation as the one you gave me, just a little more convenient

Best ResponseYou've already chosen the best response.0and from this we determine the center is (0,0) and the radius is 6
