Back

w < 5

How do you represent 'I can have no more than 10 pieces of candy' as an inequality?

Back

x ≤ 10

Front

When graphing an inequality, when do you use a closed dot?

Back

You use a closed dot when the inequality includes ≤ or ≥.

Front

What does a graph with an open dot indicate?

Back

A graph with an open dot indicates that the value is not included, used for < or >.
