Answer:
First vector

Second vector

Step-by-step explanation:
Given that
Vector a , a= 4 i + 5 j + 0 k
Vector b , b= 0 i + 1 j - 3 k
The orthogonal vector V is given as
V = a x b
V is the cross product of the above two vector which is orthogonal to the vectors a and b.

The unit vectors

First vector

Second vector

Answer:
x = -1, y = 1
Step-by-step explanation:
x + 2y = 1
Subtract 2y from both sides
x + 2y - 2y = 1 - 2y (simplify) -> x= 1 - 2y
----
-x + y = 2
Subtract y from both sides
-x + y - y + 2 - y (simplify) -> -x = 2 - y
Divide both sides by -1
=
-
(simplify) -> x = -2 + y
