Find the solution of the system of equations 8x-4y=-32 -3+4y=42

How do i make someone brainliest? (if you answer me, i might be able to make you brainliest! )

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. 4x^2 + 20x + 25 = 0

Consider the following equation. 1/2x^3+x-7=-3sqrtx-1 approximate the solution to the equation using three iterations of successive approximation. use the graph below as a starting point. a. b. c. d.
