Question

Determine a matriz A do tipo 3x2 sabendo que aij = (2i-3j)/2

Answer 1

$\left[\begin{array}{ccc}x11&x12&x13\\x21&x22&x23\end{array}\right]$

x11=(2.1-3.1)/2
x11 =-3/2

x12=(2.1-3.2)/2
x12=-4/2
x12=-2

x13=(2.1-3.3)/2
x13=-7/2

x21=(2.2-3.1)/2
x21=1/2

x22=(2.2-3.2)/2
x22=-2/2
x22=-1

x23=(2.2-3.3)/2
x23=-5/2

$\left[\begin{array}{ccc} \frac{-3}{2} &-2& \frac{-7}{2} \\ \frac{1}{2} &-1& \frac{-5}{2} \end{array}\right]$
