Question

45- Determine a matriz X em cada item​

Answer 1

Explicação passo-a-passo:

a)

$\sf X-\Big[\begin{array}{cc} \sf 7 & \sf -3 \\ \sf 4 & \sf 5 \\ \sf 2 & \sf 0 \end{array}\Big]=\Big[\begin{array}{cc} \sf 11 & \sf 9 \\ \sf 23 & \sf -8 \\ \sf 6 & \sf 3 \end{array}\Big]$

$\sf X=\Big[\begin{array}{cc} \sf 11 & \sf 9 \\ \sf 23 & \sf -8 \\ \sf 6 & \sf 3 \end{array}\Big]+\Big[\begin{array}{cc} \sf 7 & \sf -3 \\ \sf 4 & \sf 5 \\ \sf 2 & \sf 0 \end{array}\Big]$

$\sf X=\Big[\begin{array}{cc} \sf 11+7 & \sf 9-3 \\ \sf 23+4 & \sf -8+5 \\ \sf 6+2 & \sf 3+0 \end{array}\Big]$

$\sf X=\Big[\begin{array}{cc} \sf 18 & \sf 6 \\ \sf 27 & \sf -3 \\ \sf 8 & \sf 3 \end{array}\Big]$
