The length of a standard basketball court can vary from 84 feet to 94 feet, inclusive. Write an absolute value inequality that describes the possible lengths of a standard basketball court.
--------------------------
Let x be the length of the basketball court.
-------------------------
Find the midpoint between 84 and 94 which is 89
The interval for "x" must roam between 84 and 94
which means it must be within 5 of the midpoint.
-----------------
Absolute value describes distance so you have this:
The distance of x from 89 is less than or equal to 5.
|x-89|<=5
