Let x, y, z be (non-zero) vectors and suppose w = -4x-3y - z. If z = 4x + 3y, then w = -8x+-6 y. Using the calculation above, mark the statements below that must be true. A. Span (w, x) = Span(w, x, y) B. Span(w, z) = Span(w, x, z) I C. Span(w, x, z) = Span(y, z) D. Span(w, y, z) = Span(w, z) | E. Span(w, y, z) = Span(w, y)
