1. dmezzullo

Ok so i need help with an inequality thingy

2. dmezzullo

i jus need an answer checked.

3. dmezzullo

I am suppose to Describe a real life scenario where inequalities are used and state the inequality.

4. dmezzullo

Here is what i have 1 sec.

5. dmezzullo

In fl to get your permit u have to be at least 15. So would the inequality be.. lemme draw it

6. dmezzullo

|dw:1362536382003:dw| Is da right?

7. saifoo.khan

No. it can't be right. Your ineq says values can be less than 15 as well. But they CAN'T be less than 15.

8. dmezzullo

|dw:1362536653066:dw|

9. saifoo.khan

10. dmezzullo

No.

11. saifoo.khan

|dw:1362536718593:dw|

12. dmezzullo

So thats it?

13. saifoo.khan

your ineq says x is LESS than and equal to 15. Which is wrong.

14. dmezzullo

U have to be 15 and older to get ur permit/ liscense.

15. saifoo.khan

YES! So x should be GREATER or equal to 15.

16. dmezzullo

Yes^

17. phi

maybe it's easier to think concretely age ≥ 15 (rather than x)

18. phi

another example: cost for lunch ≤ dollars in pocket

19. dmezzullo

Oh ok
