    plug each point into the inequality if you get a true inequality, then that point is in the solution set

    for example, let's check choice A y≥4x - 5 4≥4*3 - 5 4≥12 - 5 4≥7 which is FALSE, so (3, 4) is NOT a solution So choice A is out

    The answer should be D because \[1\ge4(1)-5\]

    when you use c you get \[0\ge4(3)-5\] \[0\ge7\] Which isn't true so I am pretty positive it is D

    it should be infinitely many because if you put them into slope intercept form they are the same line

    The local zoo has two water tanks for the elephant exhibit that are leaking One water tank contains 12 gal of water and is leaking at a constant rate of 3 gal/h. The second water tank contains 8 gal of water and is leaking at a constant rate of 5 gal/h. When will the two tanks have the same amount of water? Explain. Let x = the number of hours the tanks are filling and let y = the number of gallons in the tank. A. In 2 hours, because the solution to the system is (2,18). B. They will never have the same amount of water because the solution to the system is (–2,18). It is not possible to have time be –2 hours. C. In –2 hours, because the solution to the system is (–2,18). D. They will never have the same amount of water because the solution to the system is (–2,18). It is not possible to have –2 gallons in the tanks.
