3. Determine whether or not u and v are linearly dependent, where (a) u (1,2) and v = (3,-5) (b) u (1,-3) and v = (-2,6) = (c) u (1,2,-3) and v = (4,5, -6) = = (d) u (2,4,-8) and v = (3,6, -12) 1 3 -4 50-1 ·( 16 ) -4 -12 16 -20 0 4 (e) u = 1) and t v = :( 1 1 1 2 2 2 and v = 2 2 2 3 3 3 (f) u = :).
