which phrases can be used to represent the inequality 12 - 3x≥9? select two options. twelve less than three times a number is greater than or equal to nine. twelve less than three times a number is at least nine. twelve minus the product of three and a number is greater than or equal to nine. twelve minus the product of three and a number is no more than nine. twelve minus the product of three and a number is no smaller than nine.
Answer
Explanation:
Step1: Analyze the inequality components
The expression $12 - 3x$ means twelve minus the product of three and a number $x$. The symbol $\geq$ means "greater than or equal to" or "no smaller than".
Step2: Evaluate each option
- Option 1: "Twelve less than three times a number" is $3x - 12$, not $12 - 3x$, so it's wrong.
- Option 2: "Twelve less than three times a number" is $3x - 12$, not $12 - 3x$, so it's wrong.
- Option 3: "Twelve minus the product of three and a number is greater than or equal to nine" correctly represents $12 - 3x\geq9$.
- Option 4: "No more than" means $\leq$, so "Twelve minus the product of three and a number is no more than nine" represents $12 - 3x\leq9$, it's wrong.
- Option 5: "Twelve minus the product of three and a number is no smaller than nine" correctly represents $12 - 3x\geq9$ as "no smaller than" means $\geq$.
Answer:
Twelve minus the product of three and a number is greater than or equal to nine. Twelve minus the product of three and a number is no smaller than nine.
