Answer:
B
Step-by-step explanation:
The closed circle at - indicates that x can equal this value
The open circle at indicates that x cannot equal this value.
All values of x between - and
are valid, thus
- ≤ x <
→ B
Answer:
See below:
Step-by-step explanation:
Hello! We can check to see if the inequality is true by replacing r with 18 as we have been told to find them in which 18 as r makes the equation true.
So our equations to test for are:
We can input 18 as r and then we see the following are correct:
1. No, as a -21 is not greater than -6
2. Yes, as -15 is less than 6.
3. No, as 21 is not greater than 6
4. No, as -15 is not greater than 6.
Cheers!
