write f(x)=1/2x^2+3/2x-5 in intercept form then find the x-intercepts, the vertexand the axis of symmetry of the graph of f

The last time i bought this product , it cost $20.00 but it looks like it cost 29. 60 today? what is the increase

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103

Simplify. (-2)^-3 a. -8 b. -1/8 c. 1/8 d. 8
