Anyone up for a jolly conversation? I'm hella bored.

3. solve by graphing: y = 2x + 6 x + y = -3

The two square pyramids are similar. find the total volume of both pyramids if the ratio of their surface areas is 9/16

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)
