a 2-mi cab ride costs $4.25. a 7-mi cab ride costs $8.50. which equation models the cost y of a cab ride that is x miles?

  • help -

    a+2b = 4.25
    a+7b = 8.50
    (a,b) = (51/20,17/20)

    so,

    y = 2.55 + .85x

    . Which ordered pair could you remove from the relation {(–2, –1), (–1, 1), (–1, 0), (0, 1), (1, 0)} so that it becomes a function?

  • math models -

    The time t required to drive a certain distance varies inversely with the speed r. If it takes 2 hours to drive the distance at 30 miles per hour, how long will it take to drive the same distance at 50 miles per hour?
