Given (x, y) coordinates, create a function such that each coordinate is uniquely mapped to an integer. also make sure that given an integer, you should be able to find (x, y) coordinates. so f(x, y) = z and also that inverse f(z) = (x, y)

The initial tableau of a linear programming problem is given. use the simplex method to solve it. x 1 x 2 x 3 s 1 s 2 z 1 2 4 1 0 0 8 3 4 1 0 1 0 10 minus3 minus12 1 0 0 1 0 the maximum is nothing when x 1equals nothing, x 2equals nothing, x 3equals nothing, s 1equals3, and s 2equals0. (be sure to simplify to lowest terms if necessary.)
