Question 803329: can you please help me figure out how to find the interval notation for this and also how to graph it on a number line
5/7x-4>0 its in fraction form, im having trouble finding the zeros and the restrictions, thank you in advance Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! 5/7x-4>0
multiply both sides of > by 7x
5 -4*(7x) > 0
5 -28x > 0
subtract 5 from both sides of >
-28x > -5
divide both sides of > by -28 and flip > sign
x < 5/28
the solutions are all real numbers less than 5/28, show this by the following
negative infinity<-------------------5/28)
this is the half open interval, -infinity,5/28)
