Let V be an n -dimensional vector space and let W C V be an m -dimensional subspace. For each v E V, define Sy = {v+ w: w e W}, and let U = {Sv : v E V}. Define addition in U so that for any x, y E V Sx + Sy = Sx+y and define scalar multiplication so that for any k E R kSx = Skx It can be shown that U is vector space (you do not need to prove this).

Based on the given information, need help explaining why the zero vector in U is a subspace of V. Thank you :)

Let V be an n -dimensional vector space and let W C V be an m -dimensional subspace. For each v e V, define
Sy = {v+ w : w e W}, and let U = {Sv : v E V}. Define addition in U so that for any x, y e V
Sx + Sy = Sx+y
and define scalar multiplication so that for any k e R
kSx
Skx
It can be shown that U is vector space (you do not need to prove this).
