## Inequality Examples Below

## Explantion

**Speed Limit**- Our speed limit around here is about 60 mph.Although people barely get pulled for going 15 over, the average citizen should go less than 60 mph.On a graph the dot would be closed with the line pointing to the left on starting on 60.

**Voting age**- The voting age for a U.S. citizen is 18 years old.somebody cannot vote even a day before the age 18. You can only vote if you are 18 years or older. On a number line, this will be a closed dot pointing to the right on the 18.

** Driver's licence**- eligibility- Somebody can only receive a licence a licence to drive during or after the age of 16.On a graph this be showed as a closed dot pointing to the right on the 16.

** Must be 48" tall to ride**- Chances are you have seen this sad sign when at your favorite amusement park. It's telling us that if you are shorter than 48'' then the ride could potentially be dangerous. So, on a number line, the closed dot would be on the 48 going to the right.

** Must be 18 years or older to order now. (as seen on TV products)**- Chances are if you have seen this person say this on a kids commercial while watching your favorite show, you cried to your parents until your head exploded to get that product, then after 10 mins it probably broke. Anyway everybody has seen something like this when growing up. On the pillow pet commercial picture above, it says must be 18 years or older to order. All it means is that to buy that product, you must be 18 years or older. On a number line there would be a closed dot on the 18 pointing right.

## Equations

Voting Age: X must be greater than or equal to 18

Drivers licence : X must be greater than or equal to 16

Must be 48" tall to ride: X must be grater than or equal to 48(")

Must be 18 years or older to order: X must be greater than or equal to 16
