  1. If you rewrite the constraints in terms of y, for example,
    2x+y≤30 as
    y≤-2x + 30
    then you can graph the constraints.
    When y≤ something, then the feasible region is below the line, if y>0, the feasible region is above the line.
    For x≥0, it is on the right of the y-axis.

    What do you get for the corner points?

    Once you have the corner points in the form of (x,y), you can evaluate
    Z(x,y) in terms of x and y and hence compare the value of Z that maximizes its value.

    There are two solutions to | 16x - 5 | = 3. The greatest solution is ___. Since the expression, 16x - 5, can be either positive or negative, solve for both. 16x - 5 = 3 16x = 8 x = .5 -(16x - 5) = 3 -16x + 5 = 3 -16x = -2 x = 1/8

    5(-3x - 2) - (x - 3) = -4(4x + 5) + 13 Answer Multiply factors. -15x - 10 - x + 3 = -16x - 20 +13 Group like terms. -16x - 7 = -16x - 7 Add 16x + 7 to both sides and write the equation as follows 0 = 0
