The columns span R* because the reduced row echelon form of the augmented matrix is which has a pivot in every row (Type an integer or decimal for each matrix element.) OB. The columns do not span R* because none of the columns of A are linear combinations of the other columns of A C. k 100 ack jey 010 154 The columns do not span R* because the reduced row echelon form of the augmented matrix is 001 000 0 not have a pivot in every row (Type an integer or decimal for each matrix element) OD.
