The coefficient matrix A = [1 -2 -3 3 1 -2 5 7 -5 -4 3 -5 -8 11 0 -1 3 4 -3 -2]

Question

The coefficient matrix A = [1 -2 -3 3 1 -2 5 7 -5 -4 3 -5 -8 11 0 -1 3 4 -3 -2] row reduces to U = [1 0 -1 0 2 0 1 1 0 -1 0 0 0 1 -1 0 0 0 0 0] true or false: the column space of A is identical to the column space of U what is the rank of the matrix A ? find linearly independent vectors which span the column space of A true or false: the row space of A is identical to the row space of U find linearly independent vectors which span the row space of A true or false: the null space of A is identical to the null space of U find linearly independent vectors which span the null space of A
