alleryA linear inequation in one variable can be written as
- a x + b > c with a, b, c real numbers
- a x^2 + b x + c = 0 with a not zero
- a x + b = c with strict equality only
- a x + b y > c with two variables only
Show answer and solution
Correct answer: A. a x + b > c with a, b, c real numbers
1. Section 4.2 lists the standard forms.
2. It uses the variable x to the first power only.
3. Inequality signs >, <, >= or <= appear instead of =.
4. So option A is correct.
