5. find the inverses of the following functions:
a. f(x) = (2 / 3 x) − 10
b. g(x) = 2(x + 4)3
c. h(x) = 1 / x−2 , xx ≠ 2

What is the perimeter of a rectangular building that is 80 feet wide and 140 feet deep?

The border line of the linear inequality 4x + 7y < 5 is dotted true or false?

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)
