What is the maximum value of [z = 8x + 7y] , subject to the conditions {2x + 4y >= 4, 2x + 3y <= 12, x >= 0, y >= 0}

  • math -

    this is a linear programming problem

    sketch the four lines
    a 2x + 4y = 4 (0,1) to (2,0) over it
    b 2x + 3y = 12 (0,4) to (6,0) under it
    c x = 0
    d y = 0
    You have a four sided figure , must be inside with corners
    (0,1)(2,0) (0,4) (6,0)

    find z at each corner
    which is biggest?
