Let x, y, z be (non-zero) vectors and suppose w= 8y-4x+4z. If z=2x-4y, then w=4x-8y. Using the calculation above, mark the statements below that must be true

A) Span(x,y)=Span(y,z)

B) Span (w,x,z)=Span(w,x)

C)Span(x,z)=Span(w,y)

D) Span(w,z)=Span(y,z)

E) Span(w,x,y)=Span(w,z)

Answer rating: 100% (QA)

Let x y z be nonzero vectors Since w and z are multiples of each other their span would be equal Sp... View the full answer
