Three classmates want to know when a tennis ball and a balloon will reach the same vertical height above the ground. David hits a tennis ball with his racquet and Tyler releases a balloon at the same time that Samantha starts a timer. Let x represent the time, in seconds, since the timer starts. The following graph shows the vertical height of the tennis ball and balloon, in feet. Which of the statements best describes the solutions to the system of equations? There is one possible solution, but it is not viable.

There are two possible solutions, and both solutions are viable.

There are two possible solutions, but only one of the solutions is viable.
