Click on the statements that are true. All replacement matrices have determinant 1. It is impossible for a swap matrix and a scale matrix to have the same determinant. There is an elementary matrix whose determinant is 0. The n × n elementary matrix realizing the scaling of a single row by a factor of α has determinant α n . The determinant of any swap matrix is -1. It is impossible for a swap matrix and a replacement matrix to have the same determinant.

The three given statements are true as below It is impossible for a swap matrix and a replacement matrix to have the same determinant There is an elementary matrix whose determinant is 0.The n×n elementary matrix realizing the scaling of a single row by a factor of α has determinant αn.

Step-by-step explanation:

To click on the given statements which is true :The three given statements are true as below It is impossible for a swap matrix and a replacement matrix to have the same determinant There is an elementary matrix whose determinant is 0.The n×n elementary matrix realizing the scaling of a single row by a factor of α has determinant αn.Option 2),3) and 5) are correct

A: 18/15b : 7 - -8 = 15 , 12 - -6 = 18 the y variable always goes over the x variables, c : same thing a
