Vectors:
Determine the value for x such that the points A(1, 3, 4), B(2, 3, 1), and C(5, 6, x) all lie on a plane that contains the origin.
answer: x=7
How do you solve this? Especially since it says it should contain the origin..

Best ResponseYou've already chosen the best response.0I don't think our teacher does it think way. She uses linear combinations to solve these questions :S so (5, 6, x) = a(1, 3, 4) + b(2, 3, 1)
