Front

What is the solution to the inequality -4b - 16 < 2b + 26?

Back

To solve, combine like terms and isolate b. The solution will be a range of values for b.

Front

What does the inequality r ≥ -6 indicate?

Back

It indicates that r can be -6 or any number greater than -6.

Front

Back

First, simplify the inequality, then find the boundary line and shade the appropriate region.

Front

What does it mean if an equation has Infinite Solutions?

Back

It means that there are countless values that satisfy the equation, often because both sides simplify to the same expression.

Front

What is the difference between Infinite Solutions and No Solutions?

Back

Infinite Solutions means many values work, while No Solutions means no value can satisfy the equation.

Front

How do you determine if an equation has One Solution?

Back

If you can isolate the variable and find a single value that satisfies the equation, it has One Solution.

Front

What is an inequality?

Back

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

Front

What does the symbol '≥' mean in inequalities?

Back
