Question

Precalculus VECTORS. Please help me and also explain how to solve . Thank you

Answer 1

You have two vectors:
`\vec{a}=(2,-1)` and
`\vec{b}=(3,3).`

In order to find the sum
`\vec{a}+\vec{b}` of vectors
`\vec{a}` and
`\vec{b}`, you should add corresponding coordinates:

`\vec{a}+\vec{b}=(2,-1)+(3,3)=(2+3,-1+3)=(5,2).`

Answer: correct choice is C.
