ok I'm looking at your last question @goopyfish908 do you see how @Kkutie7 went from \[\Large \frac{x}{-2}-8\le-2\] to \[\Large x\ge-12\] ???

  • UsukiDoll
step 1. we need x by itself step 2. multiply -2 throughout the equation. step 3. ??????????? step 4. ??????????

  • anonymous
yes, sur
jim_thompson5910
  • jim_thompson5910
how would you graph \[\Large x\ge-12\] on a number line
anonymous
  • anonymous
i dont know how to write it out on here, but yes sur
UsukiDoll
  • UsukiDoll
you could draw it out using the draw button???
jim_thompson5910
  • jim_thompson5910
you can describe it using words would you have an open circle? or closed circle? where would this circle be? would you shade to the left? or to the right?
jim_thompson5910
  • jim_thompson5910
drawing it out works as well
UsukiDoll
  • UsukiDoll
like draw on microsoft paint or some paint program and then attach the file to here so we can see the number line...that can work as well :)

close but since we have a \[ \huge \geq\] sign it means closed circle.

  • jim_thompson5910
here's a good example showing all the possibilities http://www.mathwarehouse.com/number-lines/inequality-pictures/number-line-inequality-graph-example1.png notice the > means shade to the right if you have an under line under the >, then the endpoint is a closed circle

  • anonymous
oh, i thought it was the oposite
UsukiDoll
  • UsukiDoll
\[\huge > < \] means open circle \[\huge \geq \leq \] means close circle

ok
