If Jeremy writes the equation 50 = 2d + 15, what is he trying to solve for?

Select all of the quadrants that the parabola whose equation is y=√x-4 (principal square root) occupies. i ii iii iv

A. 90 degrees b. 45 degrees c. 30 degrees d. 120 degrees

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.
