Question 71432
3x "is greater than or equal to sign" 2x - 4
:
You can write it;
3x >= 2x - 4
:
Subtract 2x from both sides:
3x - 2x >= -4
:
x >= -4
:
Graph this, it's a verticle line passing through the x axis at -4
:
The ">=" sign means that the area of feasibility is at or to the right of that vertical line
:
Make sense?
