Question 140788
finishing line is rated by pounds of strain at which it is expected to break. If a fishing line is rated at 60 lbs, the line is expected to break if a fish of about 60 lbs pulls at it. in reality, we do not expect all 60lbs lines to breat at exactly 60lbs. one manufacturer sets the specifications for their 60-pound line to have a tolerance of 5 lbs. 

a. on a number line, graph the interval for the weights at which the 60-pound line is expected to break.
Draw a number line
Mark a point "60"
Draw a solid line from 55 to 65
---------------------------------------------------
b. write a compound inequality representing the interval of the weights at which the 60-pound line is expected to break.
55 < x <  65
-----------------------

c.write an absolute value inequality representing the interval of the weights at which the 60-pound line is expected to break. 
|x-60| <= 5
====================
