(a) If A is a 3 x 4 matrix and y E im(A) then the system Ax = ỹ has infinitely many solutions. (b) Let S : R³ R' and and T : R³ R' denote two linear transformations. If the composition SoT: R³ R' is invertible, then both S and T are invertible. (c) If A and B are subspaces of R3 then A U B is a subspace of R. Note: The notation A U B is denoting the union of A and B, i.e. A U B = {i e R³ : i E A or i e B}

True or false

(a) If A is a 3 x 4 matrix and y E im(A) then the system Ax = ỷ has infinitely many solutions. (b) Let S : R3 → R and and T : R3 → R' denote two linear transformations. If the composition SoT : R' → R´ is invertible, then both S and T are invertible. (c) If A and Bare subspaces of R' then A U B is a subspace of R'. Note: The notation A U B is denoting the union of A and B, i.e. A U B = {x E R³ : i E A or i E B}
