Let $\vec{u}=\left[\begin{array}{ccc} -4 &1 &-4 \end{array}\right]$ and $\vec{v}=\left[\begin{array}{ccc} 4 &0 &-4 \end{array}\right]$. Find the vector $\vec{w}=4 \vec{u} - 5 \vec{v}$ and its additive inverse.
$\vec{w} =$ $\left[\Rule{0pt}{1.2em}{0pt}\right.$$\left]\Rule{0pt}{1.2em}{0pt}\right.$
$-\vec{w} =$ $\left[\Rule{0pt}{1.2em}{0pt}\right.$$\left]\Rule{0pt}{1.2em}{0pt}\right.$
