Question

Is (b) true or false. If true, explain why. If false, give a counterexample

(4) Determine if each of the following statements is true or false. If it's true, explain why. If it's
false explain why not, or simply give an example demonstrating why it's false. (A correct
choice of "T/F" with no explanation will not receive any credit.)
(a) If a homogeneous system has 6 equations and 5 unknowns, then there must be a unique
solution.
(b) If a m x n homogeneous system has 2 solutions, then it must have at least two basic
solutions.
(c) If A, B are matrices so that AB
BA, then A, B are square matrices of the same size.
а
(а) If A %
then AB = BA for any 2 × 2 matrix B.
