Amount discount is 8.25.
Percentage discount is 84.999%.

<h2>
</h2>

To find f(-9) , substitute the value of x that's -9 into f(x). That is for every x in f (x) replace it with - 9
We have

Time spent is independent and the amount earned is dependent should be number 1
Matrix B has dimensions 4x3
Matrix C has dimensions 3x4
Write out those dimensions like so: 4x3 3x4
The inner '3's match up so B*C is possible. The dimensions of B*C is 4x4 as these are the outer dimensions when lining up 4x3 3x4
Since B*C is a square matrix, it is possible that an inverse could exist. Keep in mind that this isn't a guarantee as the determinant of B*C could be zero (which would lead to BC being non-invertible). Though of course we'd need more info.
