(10pts) Suppose that vectors ~v 1,~v 2,~v 3 ∈ R5 and let A be the matrix whose columns are ~v 1,~v 2,~v 3. Suppose also that A −11 −1 3 2 12 0 5 −4 3 = −5 0 −2 −5 0 3 4 0 −1 −5 0 0 4 0 11 . Can you conclude fromthis information whether the vectors~v 1,~v 2,~v 3 are linearly dependent or linearly independent? Make sure to ...
