Question

given vectors $mathbf{u}=langle - 3,-4
angle$ and $mathbf{v}=langle - 4,-1
angle$, find the sum $mathbf{u}+mathbf{v}$ and write the result in component form.
answer attempt 1 out of 2
answer: $langle
angle$ submit answer

Explanation:

Step1: Add x - components

Add the x - components of vectors $\mathbf{u}$ and $\mathbf{v}$. The x - component of $\mathbf{u}$ is - 3 and of $\mathbf{v}$ is - 4. So, $-3+( - 4)=-3 - 4=-7$.

Step2: Add y - components

Add the y - components of vectors $\mathbf{u}$ and $\mathbf{v}$. The y - component of $\mathbf{u}$ is - 4 and of $\mathbf{v}$ is - 1. So, $-4+( - 1)=-4 - 1=-5$.

Answer:

$\langle -7,-5
angle$
