If False, provide an explicit counterexample
(a) Let Az = 6 be a consistent, inhomogeneous system of linear equations. A solution to the
system is given by = A-¹6
(b) Consider two maps S,T: RR". The composition SoT is a linear map if and only if
both S and T are linear maps
(c) Let S C Mn (R) be the set of n x n matrices such that the sum of all entries is zero. Then
S forms a subspace of M₂ (R).
(d) Let V be an inner product space with finite dimension n. If two non-zero vectors u, EV
satisfy the condition that (u, w) = (v, w) for all we V, then u = 7.
