2. Suppose that y varies directly with x and inversely with z, and y= 18 when x = 15 and z = 5. Write the equation that models the relationship. Then find y when x = 21 and z = 7. Sz 5 Oy = 3 Sx Oy = ; 15. Oy = -: 18 Oy = —; 2 X​

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)
