The parabola x= √y-9 opens: a.)up b.)down c.)right d.)left

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)

Given that (6,9) is on the graph of f(x), find the corresponding point for the function f(x - 2). enter the correct answer.
