On your work, you should draw the solid curve shown as a dashed curve.

    So it would be a dashed line with shading on the side that does not include the origin?

    im sorry the graph i gave you was wrong...the shading is on the opposite side the graph of the inequality -3x-y>-6 is a dashed line with shading on its left

    y > -3x + 5 6 > -3(0) + 5 .. Plug in (0,6) 6 > 0 + 5 6 > 5 which is true so it's a solution Do the same for the others

    There are others that could be the solution (you don't know until you can verify or rule them out)

    Connie needs to burn at least 500 calories at the gym today. She can burn 20 calories per minute on the treadmill (t) and 10 calories per minute on the elliptical trainer (e). Which inequality below can be used to find the possible combinations of time she could spend on each machine and still meet her goal of burning at least 500 calories? 20t - 10e 500 20t + 10e 500 20t - 10e 500 20t + 10e 500
