Mathematics

$A = \left[\begin{array}{cccc}1&-1&-3&-5\\4&2&0&-2\\7&5&3&1\end{array}\right]$

Step-by-step explanation:

A = (aij)

i representa a linha e j a coluna.

Tipo 3x4

Isto implica que a matriz tem 3 linhas e 4 colunas.

aij = 3i – 2j.

Primeira linha:

$a_{1,1} = 3(1) - 2(1) = 1$

$a_{1,2} = 3(1) - 2(2) = -1$

$a_{1,3} = 3(1) - 2(3) = -3$

$a_{1,4} = 3(1) - 2(4) = -5$

Segunda linha:

$a_{2,1} = 3(2) - 2(1) = 4$

$a_{2,2} = 3(2) - 2(2) = 2$

$a_{2,3} = 3(2) - 2(3) = 0$

$a_{2,4} = 3(2) - 2(4) = -2$

Terceira linha:

$a_{3,1} = 3(3) - 2(1) = 7$

$a_{3,2} = 3(3) - 2(2) = 5$

$a_{3,3} = 3(3) - 2(3) = 3$

$a_{3,4} = 3(3) - 2(4) = 1$

Matriz:

A matriz é dada por:

$A = \left[\begin{array}{cccc}1&-1&-3&-5\\4&2&0&-2\\7&5&3&1\end{array}\right]$
