Question

Realize a operação e marque a matriz que corresponde a resposta. *

/3 5/ + /0 -2/ - /1 1 /

/-1 2/ /1 4 / /0 0/

Answer 1

Resposta:

$=\begin{pmatrix}2&2\\ 0&6\end{pmatrix}$

Explicação passo a passo:

$\begin{pmatrix}3&5\\ \:-1&2\end{pmatrix}+\begin{pmatrix}0&-2\\ \:1&4\end{pmatrix}-\begin{pmatrix}1&1\\ \:0&0\end{pmatrix}$

Primeiro,

$\left(\begin{array}{cc}3 & 5 \\-1 & 2\end{array}\right)+\left(\begin{array}{cc}0 & -2 \\1 & 4\end{array}\right)=\begin{pmatrix}3&3\\ 0&6\end{pmatrix}$

depois,

$\begin{pmatrix}3&3\\ 0&6\end{pmatrix}-\begin{pmatrix}1&1\\ 0&0\end{pmatrix}$

$=\begin{pmatrix}2&2\\ 0&6\end{pmatrix}$
