Extracted text: 6 8 10 Let u = - 3 and A = 0 1 -1 Is u in the subset of R° spanned by the columns of A? Why or why not? -6 1 3 Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or decimal for each matrix element.) O 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.
