1. Linear Systems of Equations 3. Determine the value(s) of h such that the augmented matrix yields a consistent linear system. (b) [14-11-287. 9h] a) 1 5-4 1 0-3 8 1 0-3 81 4. The matrices 0 2 15 -9and 0 5 5are row equivalent. What is the 01 5-2 0 1 5 -2 row operation that transforms the first matrix to the second? 5. If the statement is always true, circle True. If the statement is sometimes false, circle False. In each case, write a careful and clear justification or counterexample. (a) Two equivalent linear systems can have different solution sets. True False (b) A consistent linear system must have a unique solution True False (c) The matrix 01where each represents a non-zero TrueFalse 0 0 1 real number corresponds to a consistent linear system.
