\[r \ge 1/5\]

good

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

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

I see, thank you so much :)

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

hmm looks like you switched the inequality for some reason

@satellite73 is correct !

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

havent noticed sorry.

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

|dw:1378306304230:dw|

again, im sorry for that. i havent noticed.

|dw:1378306331410:dw|

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

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

okay, thank you for your help.
