Question

Please Help!!

Let u = <-3, -5>, v = <-3, 1>. Find u + v.

Answer 1

u=-4

Answer 2

Vector addition, right?
to find the vector sum of u and v, add together the x-comps of u and v and then add together the y-comps. Know what to do next?

Answer 3

Not sure what yu mean by u=-4. u and v are vectors, each with an x- and a y-component. Thus, u=-4 has no meaning.

Answer 4

i have no clue, this is a foreign language to me

Answer 5

i didn't understand the lesson at all

Answer 6

You are studying vectors, right? What's the name of your course?

Answer 11

Adding vectors is easy.

Take two vectors each with two components, \(\vec{u}=\langle a_1,b_1\rangle\) and \(\vec{v}=\langle a_2,b_2\rangle\).

Vector addition can be broken down into the addition of each vector's components:
\[\vec{u}+\vec{v}=\langle a_1+a_2,b_1+b_2\rangle\]

Answer 12

so (-3+-3,-5+1)?

Answer 13

Yep, easy as that. Simplify and you get the answer.

Answer 14

oh my gosh, that was so simple!! Thank you sooooo much!!
