Use a graphing calculator to sketch the graph of the quadratic equation, and then give the coordinates for the x-
intercepts (if they exist).
y= -x2 + 15x - 56
a. (-7, 0); (-8,0)
c. (-7, 0); (8,0)
b. (7,0); (-8, 0)
d. (7,0); (8,0)

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)
