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.
Answer: x=32
Step-by-step explanation: 3x+18=114
We move all terms to the left:
3x+18-(114)=0
We add all the numbers together, and all the variables
3x-96=0
We move all terms containing x to the left, all other terms to the right
3x=96
x=96/3
Answer:
A. An altitude
Step-by-step explanation:
B/c B and C aren't used in graphs
Divide the total number of miles by the number of gallons to get the mpg. (miles per gallon.)
84 / 3.62 = 23.2 mpg.
Draw it on the papaer, and you will find AC=BC*cot∠B
