Answer:
⟨-5, -1⟩
Step-by-step explanation:
Vector:
A vector is given by its endpoint subtracted by its initial point.
Vector u has initial point at (3, 9) and terminal point at (–7, 5)
Then

Vector v has initial point at (1, –4) and terminal point at (6, –1).
Then

What is u + v in component form?

⟨-5, -1⟩ is the answer.
Answer:
x<-1
Step-by-step explanation:
x+7<6
-7 -7
x<-1
I'm assuming your teacher wants you to distribute. If so, then you multiply the outer term 8 by each term inside (3a and 5). After that you add.
8 times 3a = 24a
8 times 5 = 40
So 8(3a+5) becomes 24a+40
We do not combine 24a and 40 as they are not like terms. So we leave 24a+40 as it is.
