The efficiency of a motor can be measured by the percentage of the input power that the motor uses. E(c) E(c)E, left parenthesis, c, right parenthesis models the efficiency (in percentage points) of a certain motor as a function of the power input's current c cc (in amperes).

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)
