The velocity of an object fired directly upward is given by the equation V=40-18t, where t is in seconds. when will the velocity be between 22 and 31 feet per second? write and solve a compound inequality and graph the solution on a number line.

  1. 22<40-18t<31
    subtract 40 from all sides and then divide by -18. Flip the signs afterwards.
