Let u = [-10 -8 -7], A = [6 7 16 0 2 -4 1 2 1]. Is u in the subset of R^3 spanned by the columns of A? Why or why not? Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or decimal for each matrix element.) A. No, the reduced row echelon form of the augmented matrix is which is an inconsistent system. B. Yes, multiplying A by the vector writes u as a linear combination of the columns of A.
