Answer:
False
Step-by-step explanation:
the <u>dot product</u> between two vectors A and B is:
A·B=AB
where 
is the angle between the vectors, if they are parallel, this angle is zero. so 
and so the dot product is:
A·B =AB
and since 
the dot product is equal to
A·B=AB
The dot product of parallel vectors is NOT zero
The colors on the image should match the correct blank spots on the proof. Please let me know if you disagree or is confused by my choices.
X= -2
Y= -1
Z= 1
You may use solve this problem by substituting the values as well. If everything goes wrong , go for Cramer’s rule
Answer:
10
Step-by-step explanation:
2* 5/6 = x/6
10/6 = x/6
Since the denominators are the same, the numerators are the same
x=10
He would maybe have 7.5 but I insist you the answer could be 8 too
