1. Say whether or not each of the following is a linear program. If it is a linear program, then reformulate it in standard inequality form, giving the values of the vectors c and b, and the matrix A. If it is not a linear program, write a sentence or two explaining why. Note: to make your answers easier to mark, please order your vector of vari- ables by subscript. If 2 variables have the same subscript (because you have split a variable x; into x and x) list first followed by . For example: x¹ = (x₁, T2, T3, x,,5) is ordered as described. (c) minimize subject to ₁ + x₂ + x3 = 1, X2 ≤ 3, I1 - X3 > -5, F1, T3 ≥ 0, x₁ + 2x₂-3x3 2 unrestricted
