Solve each inequality and graph the solution :
$fraction numerator negative 3 x over denominator 8 end fraction minus 20 plus 2 x greater than 6$

Note:
When we have an inequality with the symbols < or > , we use dotted lines to graph them. This is because we do not include the end point of the inequality.

The graph above shows the positions of Paul and Mark during a race. Paul and Mark each ran at a constant rate, and Mark was given a head start to shorten the distance he needed to run. Paul finished the race in 6 seconds, and Mark finished the race in 10 seconds. According to the graph, Mark was given a head start of how many yards?

Solve each inequality and graph the solution :
-2.1x+2.1<6.3

Note:
When we have an inequality with the symbols < or > , we use dotted lines to graph them. This is because we do not include the end point of the inequality.

Solve each inequality and graph the solution :
2.1x≥6.3

Note:
Whenever we use the symbol ≤ or ≥ , we use the endpoint as well. So, we use complete line to graph the solution.
