Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.

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)
