Question

if ( mathbf{b}=(-4,7) ) and ( mathbf{c}=(4,-8) ), find the sum ( mathbf{b}+mathbf{c} ).
( mathbf{b}+mathbf{c}=langlesquare,square
angle )

Explanation:

Step1: Add the x - components

The x - component of \(b\) is \(-4\) and the x - component of \(c\) is \(4\). So, \(-4 + 4\).

Step2: Add the y - components

The y - component of \(b\) is \(7\) and the y - component of \(c\) is \(-8\). So, \(7+( - 8)\).

Answer:

\(\langle0,-1
angle\)
