Prove using coordinate geometry. prove that the points (0,0), (4,0), (4, 4) and (0, 4) create a rhombus and then show that the midpoints of the sides of a rhombus determine a rectangle.

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)

Do you mind if you guys me with this question i’m on number 8

Which of the following is equal to the rational expression when x is not equal to -2 or -6?
