Show that w is in the subspace of R^4 spanned by v_1, v_2, and v_3, where these vectors are defined as follows. w = [-18 11 2 -10],
v_1 = [9 -9 -1 7],
v_2 = [-4 3 -1 -7],
v_3 = [-8 7 -2 -18]
For show that w is in the subspace, express was a linear combination of v_1, v_2 and v_3. Select the correct answer below and, if necessary, fill in any answer boxes to complete your choice.
A. The vector w is in the subspace spanned by v_1, v_2, and v_3. It is given by the formula w = ()v_1, + ()v_2, + ()v_3
B. The vector w is not in the subspace spanned by v_, v_2, and v3.
