Select all the True statements. There may be multiple answer choices. Choose all possible choices. A. For any matrix A and any number r we can always define rA B. All square matrix has Adjoint C. All square matrix has transpose D. It is impossible to have a one-by-one-square matrix E. All square matrix has inverse OF. All square matrix has determinant

If B non-singular 2x2 matrices and k is a non-zero scalar. Which one of the following expressions is correct? A. The determinant of a is k times the determinant of B B. The determinant of a is 2* times the determinant of B C. The determinant of a is k³ times the determinant of B D. The determinant of a is k? times the determinant of B

Find the values of k that make the following determinant zero. 3-k| 6-k 4 7

State which property of determinants is illustrated in this equation. | 1-4 6 2 07= 5 -1 2 1-4 6 0 8 -5 5 -1 2 Choose the correct answer below. A. If a multiple of one row of A is added to another row to produce matrix B, then det B = det A. B. IfA and B are square matrices, then det AB = (det A)(det B). O C. If two rows of A are interchanged to produce B, then det B = -det A. O D. If one row of A is multiplied by k to produce B, then det B = k • det A.
