The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?

Does the point (1, sqrt 7) lie on circle shown.

How can you tell when x and y are not directly proportional?

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
