Q10 1 Point Given the primal problem: min ce s.t. Ax - b = 0 x 20, where c E R", A C Rmxn, b E RM, and a 2 0 means a; > 0 for all dimension i. We introduce A ( R" () > 0) as the multiplier of the inequality constraint, / C R as the multiplier of the equality constraint. Select all the correct statement(s) in the following. The Lagrangian is L(x, A, u) = -but(c+A u-> ) x. The Lagrangian is L(x, A, u) = -but(c+A u+A) xc. The Lagrangian is L(x, A, u) =but(c+ A u+A)x. The Lagrangian is L(a, A, u) =but(c+A u -X) ac
