Answer:

-3

Step-by-step explanation:

For a 2 by 2 matrices such as B =  [a b c d], the determinant is expressed as;

ad - bc

Given the matrices

[A] = [5 -4 3 -3]

Determinant of A  = 5 (-3) - -4(3) (if you compare with the original matrices)

Determinant of A  = -15 + 12

Determinant of A  =-3

Hence the Determinant of A  is -3
