Question

representar a matriz D =(aij) 3×2 tal que que aij =(-2) i+j​

Answer 1

Resposta:

Se for aij =(-2)*i +j

a11=(-2)*1+1=-1

a12=(-2)*1+2=0

a21=(-2)*2+1=-3

a22=(-2)*2+2=2

a31=(-2)*3+1=-5

a32=(-2)*3+2=-4

D =

-1        0

-3       2

5       -4

Answer 2

Boa tarde!

Matriz:

$\begin{bmatrix}a11&a12\\a21&a22\\a31&a32\\\end{bmatrix}$

______________________________________________________

$\mathrm{a11}\Rightarrow\mathrm{-2\times1+1}\Rightarrow\mathrm{-2+1}=\boxed{\boxed{-1}}$

$\mathrm{a12}\Rightarrow\mathrm{-2\times1+2}\Rightarrow\mathrm{-2+2}=\boxed{\boxed{0}}$

$\mathrm{a21}\Rightarrow\mathrm{-2\times2+1}\Rightarrow\mathrm{-4+1}=\boxed{\boxed{-3}}$

$\mathrm{a22}\Rightarrow\mathrm{-2\times2+2}\Rightarrow\mathrm{-4+2}=\boxed{\boxed{-2}}$

$\mathrm{a31}\Rightarrow\mathrm{-2\times3+1}\Rightarrow\mathrm{-6+1}=\boxed{\boxed{-5}}$

$\mathrm{a32}\Rightarrow\mathrm{-2\times3+2}\Rightarrow\mathrm{-6+2}=\boxed{\boxed{-4}}$

Matriz resposta:

$\begin{bmatrix}-1&0\\-3&-2\\-5&-4\\\end{bmatrix}$
