the product of -3 and a number is at least 9 -3a_> 9 is this right.
This is my last question. The rest of my homework I knew.
Yes, that's right.
Thank you Ms. Sue, have a good night.
You're welcome, Jazz. And you have a good night, too.
To determine whether the inequality -3a ≥ 9 is correct, let's break it down and understand it step by step:
The problem statement states that "the product of -3 and a number (let's call it 'a') is at least 9."
To translate this statement into an algebraic inequality, we need to identify the relationship between the product of -3 and a and the number 9.
When we multiply a number by a negative value (in this case, -3), the inequality sign flips.
So, we can rephrase the problem statement as:
(-3) multiplied by 'a' is less than or equal to 9.
This can be written as:
-3a ≤ 9
Hence, your proposed inequality, -3a ≥ 9, is not correct. We should use -3a ≤ 9 to accurately represent the given statement.
