Determine if the statement is true or false, and justify your answer. if a is an n × n matrix and b ≠ 0 is in rn, then the solutions to ax = b do not form a subspace. true. since a0 = 0 ≠ b, 0 is a solution to ax = b, and hence the set of solutions is not a subspace. true. since a0 = 0 ≠ b, 0 is a not solution to ax = b, and hence the set of solutions is not a subspace. false. since a0 = 0 ≠ b, 0 is a solution to ax = b, and hence the set of solutions is a subspace. false. since a0 = b, 0 is a solution to ax = b, and hence the set of solutions is a subspace. false. since a0 = 0 ≠ b, 0 is not a solution to ax = b, and hen
