The MMT Observatory on Mt. Hopkins in Arizona has a primary mirror that is 6.5 meters in diameter. One of the Keck Telescopes on Mauna Kea in Hawaii has a primary
mirror that is 10 meters in diameter. Calculate the collecting area for the two telescopes. How much greater is the collecting area of the Keck telescope than the MMT?

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)
