\( \definecolor{colordef}{RGB}{249,49,84} \definecolor{colorprop}{RGB}{18,102,241} \)
Calculate \(-3\vec{u} + 5\vec{v}\) where \(\vec{u} = \begin{pmatrix} 2 \\ 0 \end{pmatrix}\) and \(\vec{v} = \begin{pmatrix} -1 \\ 4 \end{pmatrix}\).
\(-3\vec{u} + 5\vec{v} = \begin{pmatrix} \input{124584}{}{3em}{2em}{}{} \\ \input{224584}{}{3em}{2em}{}{} \end{pmatrix}\)
