Homework Help: algebra

Posted by Shawn - tricky question on Monday, August 20, 2007 at 5:22pm.

1/3x > 2 and 1/4x > 2

both are less than one so how do i graph this on the number line?

I'm confused.

I will assume you meant (1/3)x>2 and not 1/(3x)>2

With that assumption, you would get x>6 AND x>8

x>6 is a line to the right of 6, excluding the 6
x>8 is a line to the right of 8, excluding the 8

So the intersection, or all elements that belong to BOTH, would be all those to the right of 8, exluding the 8, since 8 satisfies the first but not the second

so draw on open circle around the 8 then a line to the right of it, with an arrow at its end
