Consider the kth iteration of the simplex method as defined in Algorithm 4.2 of the textbook. (a) Show that the matrix Ak+1, def
ined by replacing the sth row of Ak by the tth row of Ak is nonsingular. (The index t Wk is such that ak = σ, and the tth constraint is called a blocking constraint.) (b) Show that the component of the Lagrange multiplier λ, at xk+1 corresponding to the new constraint in the working set must be positive. (This implies that it is impossible to delete the constraint that was just added.)

Answer:
Step-by-step explanation:
We can divide polynomials by other polynomials by dividing each term by the denominator. Remember, when we divide a variable by itself, we must change the exponent in our answer according to exponent rules.
