True False If AB C then NullC NullB True False A and A1 hav

True False If AB = C, then Null(C) Null(B). True False A and A^-1 have the same eigenvectors. True False If P is a plane in R^3, then P is a subspace of R^3. True False If Av = v for some vector v, then 1 is an eigenvalue of A. True False If u, v, w are linearly dependent, then w is a linear combination of u and v.
