Along distance runner starts at the beginning of a trail and runs at a rate of 4 miles per hour. three hours later, a cyclist starts at the beginning of the trail and travels at a rate of 19 miles per hour. what is the amount of time that the cyclist travels before overtaking the runner?

do not do any rounding.

(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)
