Two friends are hiking on a mountain trail. Dale leaves at 11:00 am and starts on a pace of 4km/hr. One hour later Stacy starts out on the same trail at a pace of 6km/hr. What time will Stacy to catch up to Dale?

(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)
