Based on the Gauss-Jordan Elimination method, and the matrix given, the next step would be to b. divide R2 by 2 and R3 by 3.
<h3>What is the next step in the Gauss-Jordan Elimination method?</h3>
The first row has already gone as low as it can so rows two and three need to be worked on.
The best way to do this is to divide Row 2 by 2 and Row 3 by 3. This then leads to the augmented matrix becoming:
[1 0 0 I 5]
[0 1 0 I 4]
[0 0 1 I 3]
In conclusion, option B is correct.

To check:put value of m and n in both equations
Answer:
|8|
Step-by-step explanation:
Let the integer = x
x = - 2x - 24
x + 2x = - 24
3x = - 24
x = - 24/3
x = - 8
Hence, the integer is - 8
The number could be the positive of negative of 8
Hence, it is better expressed as |8|
Answer:
1000 : 199 : 271
Step-by-step explanation:
A rations a form of comparison between different variables or quantities.
We want to compare how much water, sucrose and saline solution are used to make the medicine.
The amount of water used is 1 L = 1000 mL
The amount of sucrose used is 199 mL
The amount of saline solution used is 271 mL
Therefore, the ratio of water to sucrose to saline solution is:
1000 : 199 : 271
This is the simplest form because 1000, 199 and 271 do not have any common factors.
6.
the y-intercept is 4, which means the line crosses the y-axis at the point (0,4).
[just put a dot on the number four that's right under the letter y]
the slope of the line is positive, so it goes up from left to right.
Start at the y-intercept. Move up 2 and then move right 1.
You are now at the point (1,6).
[go to 1 for the horizontal line, then go up 6 spaces.] [connect two points]
7. y= -1/2-3
8. y=3x+4
