The speed limit on a city street is 30 miles per hour. Define a variable for the speed. Identify the inequality and the graph that represents the speed limit.
A: [tex]0\leq x\leq 30[/tex]
B: [tex]0\leq x\ \textless \ 30[/tex]
C: [tex]0\geq x\geq 30[/tex]
D: [tex]0\geq x\ \textgreater \ 30[/tex]

I know the answer, I just want to see everyone else's opinion.
