Linear Inequations Flashcards
1
Q
How is a linear equation in one variable written?
A
ax + b < 0; ax + b ≤ 0; ax + b > 0; ax + b ≥ 0
2
Q
Name the things you can do to an inequation
A
- Add or subtract the same number or expression to both sides
- Any number or expression can be transported from one side to the other side with the sign changed
- Multiply or divide both sides by the same positive no.
3
Q
What happens when both sides are multiplied or divided by the same negative number?
A
The symbol of the inequation is reversed
4
Q
Give the steps of solving a linear inequation
A
- Simplify both sides by removing group symbols and collecting like terms
- Remove fractions or decimals by multiplying both sides by LCM of denominators or power of 10
- Isolate all variable terms on one side and constants on the other
- Make the coefficient of the variable 1
- Choose the solution set from the replacement set
