Let A [-15 45] [ -5 15] and w [3] [1] Determine if W is in Col(A), is w in Nul(A)?

Question

Determine if w is in Col(A). Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

• A. The vector w is not in Col(A) because w is a linear combination of the column

B. The vector w is in Col(A) because Ax = w is a consistent system. One solution is x=.

C. The vector w is not in Col(A) because Ax = w is an inconsistent system. One row the reduced echelon form of the augmented matrix [A 0] has the form [0 0 b] where b =.

D. The vector w is in Col(A) because the columns of A span R2.
