Which quadrilateral can be inscribed in a circle?

For the function, f(x) = -5x 2, find f(-4).

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)

What is the anwers for 9+2x=5x-3-x
