How do i multiply the two problems in the question

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points)part b: is the point (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)

What are the solutions of the equation x4 + 6x2 + 5 = 0? use u substitution to solve.
