HELP QUICK The number of miles that can be driven is proportional to the number gallons of gas. The graph of the equation y = 31x shows this relationship.
Explain why the ordered pair (0, 0) is on this graph.
A. When the tank is full, 0 miles can be driven.
B. When 0 miles are driven, there is no gas used.
C. When there is no gas in the tank, 0 miles can be driven.
D. When the tank is full, the driver does not have to worry about how much gas is used?

What is the value of x in the equation 2(x-4) = 4(2x + 1)?

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.

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)
