Mr. Burnam decided to go hot air ballooning for his fortieth birthday. He launched from 10 feet above the ground and then ascended to 75 feet above the ground. He made a descent of 55 feet toward a small valley, then made the same descent again. After these changes in altitude, was Mr. Burnam’s altitude compared to ground level?

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
