Find the decomposition a = ajb + amb with respect to b if a = (x, y, z), b = (-1, -1, 1). (Give your answer using component form (*, *, *). Express numbers in exact form. Use symbolic notation and fractions where needed.) ajb = amb =Find the projection ujv = (x, y) of u = (4, -3) along v = (1, 2). (Use symbolic notation and fractions where needed.) X =
