Determine if the statement is true or false, and justify your answer. If u1, u2, u3 is linearly independent, then so is (ui, u2. u3. u4) True. If u1. u2, u3ł is linearly independent, then the equation xu1 + xzu2 + x3u3 0 has a nontrivial solution, and therefore so does x1U + xzu2 x3u3 False. Consider for example u1 = 0 False. Consider for example u4 = 0. True. The echelon form of the augmented matrix [u1 u2 u3...
