y=$283
Answer:
Determinant are special number that can only be defined for square matrices.
Step-by-step explanation:
Determinant are particularly important for analysis. The inverse of a matrix exist, if the determinant is not equal to zero.
How to find determinant
For a 2×2 matrix
For a 3×3 matrix
we first decompose it to 2×2
Example
Find the values of λ for which the determinant is zero
Equating the determinant to zero
s = * (1 ±5 )
s = 1.61 or -0.61
It is A because if you subtract 9 and 6 you get 3 and then you add the 4 and get 7
