What inequality represents at most?
The notation a ≤ b or a ⩽ b means that a is less than or equal to b (or, equivalently, at most b, or not greater than b). The notation a ≥ b or a ⩾ b means that a is greater than or equal to b (or, equivalently, at least b, or not less than b).
What are the most common inequality symbols?
- ≠ = not equal to.
- > = greater than.
- < = less than.
- ≥ = greater than or equal to.

- >: “greater than”
- ≥: “greater than or equal to”
What does R mean in inequalities?

How do you find the inequality?
To solve an inequality, isolate the variable on one side with all other constants on the other side. To accomplish this, perform opposite operations to manipulate the inequality. First, isolate the x by multiplying each side by two. Whatever you do to one side you must also do to the other side.

How do inequality signs work?
The inequality symbol remains in the same direction. Any number 6 or greater is a solution of the inequality 4x – 3 ≥ 21. … Dividing by a negative number means you reverse the inequality symbol. Any number greater than 1 is a solution of the inequality 16 – 5x < 11.
How are inequalities used in real life?
