(-7)*(2/5 + (-3/7))
= -14/5 + 3
=1/5
Answer: 18≤n≤38 is absolute value inequality for the problem.
Step-by-step explanation:
Given situation:- Half of a number n is at most 5 units from 14
that means the difference between 14 and half times n is less than 5

⇒18≤n≤38 is absolute value inequality for the problem.


The first equation gives

Differentiating with respect to
gives

for some constant
. So

and by the fundamental theorem of calculus,
