Q9 q9.) select the correct choice below and, if necessary, fill in the answer box to complete your choice.

The first step is to find the determinant of the matrix:

using ad-bc you get (-1*3) -  (-5*5) = = -1*3 + 5*5 = 22

now the numbers inside the matrix become fractions with the determinant as the denominator
 so you get -1/22, 5/22, -5/22 and 3/22

and replace them in reverse order

3,22, -5/22 , 5/22, -1/22

The correct answer will be d. -4
