True/False: Give a brief justification for your answer a) If an m x n matrix A has a pivot position in each row, then the equation Ax=b has a unique solution for each b in R^m. b) If {u,v,w} is linearly independent, then u, v, w are not in R^2. c) If A is a 5 x 4 matrix, then the linear transformtion x -> Ax is not onto.
