Solve the following non-linear system of equations algebraically. y = - 2x² - 4x + 5 and
y = 2x^2 + 4x + 5

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.

Asystem of equations has 1 solution.if 4x-y=5 is one of the equations , which could be the other equation ?

What is the x-intercept and y-intercept of the equation 2x+1. 2o
