Tom went on a bike ride to the store 3 miles away. If it took Tom 12 of an hour to get there and 23 of an hour to get back, what was his average rate of speed (miles per hour) for the entire trip?

Part a: explain why the x-coordinates of the points where the graphs of the equations y = 2−x and y = 8x+4 intersect are the solutions of the equation 2−x = 8x+4. (4 points) part b: make tables to find the solution to 2−x = 8x+4. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 2−x = 8x+4 graphically? (2 points)
