Sample question 1
The standard form of a linear equation in one variable is:
- ax + b = 0, where a ≠ 0
- ax2 + b = 0
- a/x + b = 0
- ax + by = 0
Answer: A. A linear equation in one variable can be written as ax + b = 0 with a ≠ 0.
Sample question 2
When both sides of an inequality are multiplied by a negative number, the inequality sign:
- becomes ≠
- stays the same
- becomes =
- is reversed
Answer: D. For example, −2 < 5 becomes 6 > −15 after multiplying by −3.
Sample question 3
Solve 2x + 3 > 7 or 4x − 1 < 3.
- 1 < x < 2
- x > 1
- x > 2 or x < 1
- x > 2 and x < 1
Answer: C. The first gives x > 2 and the second gives x < 1. With 'or', we join the two sets.
