Question

Special precision bolts are made by another machine. These are for jobs that require more exact measurements. The bolts must be within 0.01 mm of 8 mm. This is represented by |x – 8| < 0.01. 


Write this inequality as a compound inequality without absolute value bars.

Solve the inequality.
Graph the solutions on a number line.
What do the solutions of the inequality mean for the bolt?

Answer 1

The solutions of the inequality is 7.99<x<8.01. I think this solutions means the radius of hole in the bolt or something along that, but I'm not sure.
