Twice a number c is at least -8. Write it as an inequality.
I'm thinking its 2c≥-8
Am I right?
It's right.
thank you, this helps :)
Yes, you are correct. The inequality is 2c ≥ -8.
Yes, you are correct! The inequality that represents "Twice a number c is at least -8" is indeed 2c ≥ -8.
To explain how we arrive at this answer, let's break down the problem into smaller steps:
1. Start with the phrase "Twice a number c": This means we have a number c that we want to double.
2. Next, consider the phrase "is at least -8": This indicates that the result of doubling the number should be greater than or equal to -8.
Combining these two parts, we can express the original statement as "2c is greater than or equal to -8." Mathematically, we write this as 2c ≥ -8.
