A hot air balloon is 10 meters above the ground and rising at a rate of 10.5 meters per minute. Another balloon is 250 meters above the ground and descending at a rate of 14 meters per minute.

a. Define variables for this problem.

x =

y =

b. Write a system of equations to represent the height of the balloons at any given time.

c. Put the equations into a graphing calculator. Use the calculator to solve the system of equations.

d. Explain what the solution means in the context of this problem.

I managed to get the variables down but the rest of the problem has me confused. I would really appreciate any help on this problem.
