The graph shows the amount of water remaining in a tank after a leak occurs. Identify the x-intercept of the function.

• (0, 10)

• (0, 0)

• (20, 0)

• No solution

The graph shows the amount of water remaining in a tank after a leak occurs. Describe the point (20, 0).

• After 20 hours the tank will be empty (0 gal).

• After 20 gallons the tank will have 0 hours.

• After 20 miles the car will have no gas.

• The car runs out of gas after 20 miles.

The graph shows the amount of water remaining in a tank after a leak occurs. Write an equation that expresses the amount of water in the tank, a, as a function of the number of hours, h, since the leak occurred.

• $a=\frac{1}{2}h+10$
  

• $a=\frac{1}{2}h+15$

• $a=-\frac{1}{2}h+10$

• $h=\frac{1}{2}a+15$

• $51

• $60

• $42
