Let A be a 5 × 4 matrix with a pivot in each column. Is A invertible? Why or why not?
1 answer:
Answer:
Matrix A is not invertible.
Step-by-step explanation:
Invertible matrix are those matrix which are square matrix or non singular matrix.
For any matrix to be invertible, matrix should be non singular i.e. det(x) 0.
But for the question given above we cannot find determinant of matrix A as it is not square matrix. so inverse of given matrix does not exist. so it is not possible to have non trival solutions.

Determine the translation rule
Considering the x coordinates.
From 17 to 6
6 is to the left of 17.
Using the translation rule:
<em>Hence: From 17 to 6 is 11 units left translation</em>
Considering the y coordinates.
From -9 to 2
2 is at the top -9.
Using the translation rule:
The negative value impies a upward translation.
Hence: From -9 to 2 is 11 units up translation
