What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other.

How do you solve the inequality 25 < X - 10?

Back

To solve, add 10 to both sides: 25 + 10 < X, which simplifies to X > 35.

Front

What does the symbol '≤' mean in inequalities?

Back

The symbol '≤' means 'less than or equal to'.

Front

What is the solution to the inequality -169 ≤ 8m - 9?

Back

Add 9 to both sides: -160 ≤ 8m, then divide by 8: m ≥ -20.

What is the first step to solve the equation 2(x - 3) = 6?

Back

Distribute the 2: 2x - 6 = 6.

Front

What is the solution to the equation 2(x - 3) = 6?

Back

The solution is x = 6.

Front

What does it mean for two expressions to be equivalent?

Back

Two expressions are equivalent if they have the same value for all values of their variables.

Front

What is the equivalent expression for 10^-12?

Back

The equivalent expression is 1/10^12.

Front

How do you graph the inequality 77 ≤ 5 + 8n?

Back

First, solve for n: 8n ≥ 72, then n ≥ 9. Graph a closed circle at 9 and shade to the right.
