Describe all solutions of Ax = 0 in parametric vector form, where A is row equivalent to the given matrix. 3-12 9 -1 4-3 x= x₂ + x3 (Type an integer or fraction for each matrix element.)

Show that no 22 matrices A and B exist that satisfy the matrix equation. AB-BA=1001.

Determine if the statement is true or false. If the statement is false, then correct it and make it true. A 75 matrix has 5 rows.

Let A be an nn matrix in which the entries of each row sum to zero. Find |A|.

Explain the difference between a square matrix and its determinant. Give an example of each.

Solve: {4x3z=53y+2z=73x+4y=6 .
