Question 82248: Hi,
I'm having trouble in a section where we are to graph a parabola with horizontal and vertical axis. For example, the problem x=y^2-10y+30. I got the vertex (5,5) and since a=1 I know it opens to the right. I know for any constant d, the points on the parabola with y-coordinates 5-d and 5+d have the same x-coordinate. So I plug in 1 and have the y coordinates as ( ,4) and ( ,6). My problem is, I can't find the constant x-coordinate. I don't know how to get the x-coordinate. Can someone please help me figure out how to find the x-coordinate in this problem. I've tried everything and can't figure it out. Thanks so much!

Question 83412: A circle contains the points (0,0), (-7,-17), and (18,-12). Solve a system of three equations in h,k, and r and give the equation of the circle. Show work. (The teacher gave the hint: Use given (x,y) pairs in to get 3 equations to solve the system using substition or elimination. I tried to do this, but got stuck...can you do both substitution and elimination in the same problem?)
