Hello,
2x-4=0==>x=2
f(2)=|2*2-4|=0
Minimum is (2,0)
Answer A
Y = mx + b...subtract b from both sides
y - b = mx...now divide both sides by x
(y - b) / x = m
I hope this is right but:
Let n=number of full time employees
260<=20+n*40
260-20<=N*40
240<=n*40
n>=240/40
n>=6 full time employees
which means he would have to hire at least 6 or more fully time employees
Though I'm not sure if the attached file is the graph you are looking for
1700m is the correct answer
