Lot H = Span (2) and B* (V.2) Show that is in H, and find the B-coordinate vector of x, whon Vy, Y2, and x are as below. 10 13 15 -7 -9 V, 9 12 14 6 9 11 Reduce the augmented matrix V, V x to reduced echelon form x] to 10 13 15 -4-7-9 9 12 14 6 9 11 How can it be shown that is in H? OA. The augmented matrix in upper triangular and row equivalent to [ B x ]therefore x is in H becauno His the Span (Vxz) and B= (v2) OB. The augmented matrix shows that the system of equations is consistent and therefore x is in OC. The last two rows of the augmented matrix has zero for all entries and this implies that must be in H. X OD. The first two columns of the augmented matrix are pivot columns and therefore x is in This moles that the B-coordinate vector is [x] =
