Solve the problem.Michael decides to walk to the mall to do some errands. He leaves home, walks 3 blocks in 11 minutes at a constant speed, and realizes that he forgot his wallet at home. So Michael runs back in 8 minutes. At home, it takes him 3 minutes to find his wallet and close the door. Michael walks 5 blocks in 15 minutes and then decides to jog to the mall. It takes him 6 minutes to get to the mall which is 2 blocks away. Draw a graph of Michael's distance from home (in blocks) as a function of time.  

What will be an ideal response?

Use Gaussian elimination to find the complete solution to the system of equations, or state that none exists.5x + 2y + z =-112x - 3y - z=177x - y=12
