Question

Construct a 3×3 matrix aij=3j-2i​ Hellpppp ASAP

Answer 1

`a_(ij)=3j-2i` is the formula for (i, j )-th entry (row i, column j ) of the matrix. So the matrix would be

`\begin{bmatrix}3*1-2*1&3*2-2*1&3*3-2*1\\3*1-2*2&3*2-2*2&3*3-2*2\\3*1-2*3&3*2-2*3&3*3-2*3\end{bmatrix} = \begin{bmatrix}1&4&7\\-1&2&5\\-3&0&3\end{bmatrix}`
