Answer:
Yes. r = 8 satisfies the inequality.
Step-by-step explanation:
From the given data, we have:
[tex]$r - 3 \leq 9 $[/tex]
adding 3 on both sides of the inequality, we have:
[tex]$ r \leq 12 $[/tex]
This means 'r' can take any real number value that is less than or equal to 12.
Since, r = 8 is less than 12, it can be a potential value for 'r'.
Another approach would be to substitute r = 8 directly in the inequality.
We would have: 8 - 3 ≤ 9
⇒ 5 ≤ 9
Since, 5 is less than 9, r = 8 satisfies the inequality.
