A Is a singular matrix, the system Ax Is Inconsistent. 2. If A is an invertible upper triangular matrix, then A¬1 is lower triangular. 3. If A and B are symmetric matrices, then A – Bis not necessarily symmetric. 4. If A and B are square matrices satisfying det(A) = 0 and det(B) = 0, then A + B cannot be invertible. 5. The linear system Ax b will have a solution for all b in R" as long as the columns of the matrix A span R"
