Answer:
A lies along the positive x-axis and B lies along negative x - axis
.
Step-by-step explanation:
They tell us that we have two vectors, A and B. And they give us a series of conditions for this, now, what would be the correct possibility.
A lies along the positive x-axis and B lies along negative x - axis
.
This is because when both vectors will be in x axis but opposite to each other, then the angle between them will be 180 ° and cos180 ° is -1.
Answer:
y = -3
Step-by-step explanation:
4x – 3y = 17
x = 2
4(2) - 3y = 17
8 - 3y = 17
-3y = 9
y = -3
