Can this be solved??
I can't get pass y=sqrt(-x^2+9)
The system I am submitting answers to says that there is a positive and a negative square root, and that the answers must be numbers. I have to find two solutions to both x and y.
Could someone just point me in the right direction as to steps to solve this?
I have a test Teus and I am so afraid I will flunk, help
Being that I am given no coordinates, that doesn't really help me. I guess the answer is an equation, but I do not do well with a ton of meaningless variables :/
Must I find a center first?
there is no "solving" here ... the equation is a circle of radius 3 centered at the origin.
oh, answers were -3 and 3 for both x and y(Bow)
... that is only one of an infinite number of solutions.

So any (x,y) Cartesian coordinate that is 3 units away from the origin is a solution.
