Question 1001639: Let A = [-4 -6]
[ 6 9]
Find the value of the determinant of A. Does this matrix have an inverse?
Please enter your answer as a list of the form: [ d, i ]
where d is the exact value of the determinant of A, and i is either y (for `yes', A has an inverse) or n (for `no', A doesn't have an inverse).
I am really not sure how to go about this.
THANK YOU

.
[0, n]

in this form.

Determinant = 0 (you can easily calculate it yourself if you know what the determinant is).
