AB will be an Identity matrix.
<h3>
What is an identity matrix?</h3>
- A square matrix with 1s on the main diagonal and 0s everywhere else is an identity matrix.
- The identity matrices 22 and 33, for example, are presented below.
- These are known as identity matrices because they produce the identity matrix when multiplied by a compatible matrix.
- If the answer to a matrix multiplication problem is an identity matrix, then each of the two matrices is an inverse matrix of the other.
- When the matrix is multiplied by the original matrix, the result is the identity matrix.
As it is given in the description itself, if the answer to a matrix multiplication problem is an identity matrix, then each of the two matrices is an inverse matrix of the other.
Therefore, AB will be an Identity matrix.

First of all, we need to deduce the price of a single camera:
Now, we know that he profits 36 dollars from each camera. So, we are asking: which percentage of 150 is 36? We have
This equation literally says: 36 is x-percent of 150. And we need to solve for x:
Answer: 30x-18
Explanation:
You are to multiply the 6 times 5x and -3
6*5x=30x
6*-3=-18
I hope this helps you
2x+4y=10
5x-4y=11
2x+4y+5x-4y=10+11
7x=21
x=3
y=1
