Multiplying the matrices A and B would yield the following matrix:
| 1 0 |
| 0 1 |
A simple method would be using a calculator to solve for this. You can input the values of one matrix, and then the values of another matrix, then multiply them and it would yield the above result. As a rule of thumb, you make sure to only multiply similar matrices.
Common factor is an expression that is common. Her we can see 2x+5 is a factor for both of the terms so it is the common factor.
The last one is the correct answer !!
D!
y-1= ±3/10(x-2)
Im not sure how to get this answer but my teacher gave it to me so i hope this helps!
