Guida verificata passo dopo passo1
Understand the phrase "at least 5" in the context of inequalities. It means the value of the variable should be 5 or greater.
Translate the phrase into a mathematical inequality. "At least 5" means the variable x is greater than or equal to 5.
Write the inequality using the appropriate symbol for "greater than or equal to": \(x \geq 5\).
Recognize that this inequality includes the value 5 itself and all values greater than 5.
Compare this with other options: \(x > 5\) excludes 5, \(x < 5\) and \(x \leq 5\) represent values less than 5, so they are incorrect.
