Question 69120
I'm having a hard time deciphering your drawing. I'm assuming you drew a number line with a point at 20, is that correct so far? The hard part is determining whether you have a closed or open circle at this point, and which direction the arrow is pointing. If its a open circle, then the inequality symbol is either > or <. If its an close circle, then it looks like this {{{x<=y}}} or {{{x>=y}}}. So lets say its a closed circle on 20 with the arrow pointing towards 21,22,23,etc then it will look like
{{{x>=20}}} (in other words x can be 20,21,22,etc)
If pointing in the opposite direction then it will look like
{{{x<=20}}} x can be anything less or equal than 20
If its an open circle, then use the < or > symbols. Hope this helps.
