Find the value of y when x = -5

Which number line represents the solution set for the inequality -1/2x> 24?

For the quadratic function [tex]y=(x+4)^2-1[/tex] , do the following: a) rewrite the function in the standard form, b) rewrite the function in intercept form, c) find the vertex, d) find the y-intercept, e) find the x-intercepts.

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 5x^2 + 10x
