• This Question is Closed
1. Coolsector

so you want to have only r on one side. subtract 4 from both sides and then divide both sides by 5. what do you get ?

2. aubreyk9616

$r \ge 1/5$

3. Coolsector

good

4. Coolsector

the graph will look like : |dw:1378306008085:dw|

5. Coolsector

the circle of 1/5 is full since r is also equal 1/5

6. aubreyk9616

I see, thank you so much :)

7. Coolsector

if we would have r > 1/5 the circle was blank

8. satellite73

hmm looks like you switched the inequality for some reason

9. Coolsector

@satellite73 is correct !

10. satellite73

if you started with $5r+4\leq 5$ then you should end up with $r\leq \frac{1}{5}$

11. Coolsector

havent noticed sorry.

12. satellite73

"less than or equal to" keep the inequality the same (unless you multiply by a negative number, then switch it)

13. aubreyk9616

ohh I though you where supposed to, I got what I did wrong your only supposed to switch with a negative

14. Coolsector

so the answer r<= 1/5 the graph will be :

15. Coolsector

|dw:1378306304230:dw|

16. Coolsector

again, im sorry for that. i havent noticed.

17. aubreyk9616

|dw:1378306331410:dw|

18. aubreyk9616

at least tryed drawing it didn't work out to well

19. Coolsector

it is ok if the bold starts at +1/5

20. aubreyk9616

okay, thank you for your help.

21. Coolsector
