Multiplication of determinants by a scalar

WebAnswer. For this question, we have been given a 2D vector and asked to perform a multiplication by the scalar quantity of 3. In order to do this, we can simply multiply both the π‘₯ and the 𝑦 component of the vector by the given scalar: 3 ⃑ 𝐴 = 3 ( βˆ’ 1, βˆ’ 8) = ( 3 ( βˆ’ 1), 3 ( βˆ’ 8)) = ( βˆ’ 3, βˆ’ 2 4). With some simplification ... WebBy the second property of determinants if we multiply one of those rows by a scalar, the matrix’s determinant, which is 0, is multiplied by that scalar, so that determinant is also 0. q.e.d. Theorem 2. The determinant of a matrix is not changed when a multiple of one row is added to another. Proof.
