Ms. Austin wrote the expression below on the chalkboard for her class. She asked the students to write an equivalent expression using no more than one set of parentheses. 4(3x + 5y + 2z) + 3(x - z)

Tom wrote 12x + 20y + 8z
Jenna wrote 5(3x + 4y + z)
Chris wrote 15x + 20y - 5z

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part 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 (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
