SOLVED:The augmented matrices that follow are in row echelon form. For each case, indicate whether the corresponding linear system is consistent. If the system has a unique solution, find it. (a) ( 1 2 4 0 1 3 0 0 1) (b) ( 1 3 1 0 1 -1 0 0 0) (c) ( 1 -2 4 1 0 0 1 3 0 0 0 0) (d) ( 1 -2 2 -2 0 1 -1 3 0 0 1 2) (e) ( 1 3

The augmented matrix for a linear system is given in which the asterisk represents an unspecified real number. Determine whether the system is consistent, and if so whether the solution is unique. Answer "inconclusive" if there is not enough information to make a decision. (a) [ 1 * * * 0 1 * * 0 0 1 1] (b) [ 1 0 0 * 1 0 * * 1 *] (c) [ 1 0 0 0 1 0 0 1 1 * *
