. Determine whether the vectors (5, −2, 4), (2, −3, 5), and (4, 5−
7) are linearly independent or dependent.

The vectors are linearly dependent.

The solution is in the attachment

The vectors are linearly independent

Step-by-step explanation:

These vectors can be written in a matrix form as:

and if the matrix is invertible, the system has a unique solution,  and hence, the vectors that form the matrix are linearly independent.

A matrix is invertible if it's determinant is different from zero.

Suppose A is a matrix, A is invertible if |A| ≠ 0

=

=

Since this is not zero, we conclude that the vectors are linearly independent.
