Which graph shows the solution to the system of lnequalities x-4y≤4 y<x+1

In the coordinate plan (-6,9) b (3,9) c (3,3) def is shown in the coordinate plan below

The height of a flare fired from the deck of a ship in distress can be modeled by h(t)= -2(8t^2-52t-28), where h is the height of the flare above water and t is the time in seconds. a. find the time it takes the flare to hit the water.

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.
