Answer:
To solve a system of of linear inequalities, you could do the elimination method or substitution method.
Step-by-step explanation:
- For elimination method, you can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.
For substitution method, you have to:
Step 1 : First, solve one linear equation for y in terms of x.
Step 2 : Then substitute that expression for y in the other linear equation.
Step 3 : Solve this, and you have the x -coordinate of the intersection.
Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.
115 is the outlier, and it results in the mean being lower than it would have been.
