Let a = i - k, b = xi + j + (1 - x) k and c = yi + xj + (1 + x - y)k. Then [a,b,c] depends on

Let bara = i - k, barb =x i+ j + ( 1 - x) k , and barc = yi + xj + ( 1 + x - y ) k . Then bara ,barb and barc are non-coplanar for

If vec a = i-k, vec b = i+j+(1-x)k and vec c = yi+xj+(1+x-y)k then [vec a vec b vec c] depends on

If a = 3i - 2j + k, b = 2i - 4j - 3k, c = -i + 2j + 2k then a + b + c =

If a = 2i - j + 3k, b = -i + 4j - 2k, c = 5i + j + 7k and xa + yb = c then (x, y) =
