Answer:
denotes amount of food that Felicity's dog eats
Step-by-step explanation:
Given:
Felicity's dog eats no more than two cups of dog food per day.
Felicity's dog eats at least one-quarter cup more than one-half of the amount Martin's dog eats.
The amount of food that Martin's dog eats is represented by using 
To find: the inequality that represents the situation
Solution:
Amount of food that Martin's dog eats =
Amount of food that Felicity's dog eats ≤ 2
Also,
Amount of food that Felicity's dog eats 
Therefore,
Amount of food that Felicity's dog eats ≤ 2
Let denotes amount of food that Felicity's dog eats.
≤
C=3.14 x 26
C=81.64
C=2(3.14 x 13)
C=81.64
The answer is a vertical line on the negative -2 (x-axis).
1. 40 units___16 workers
20 units___x= 8 workers
(20*16)/40=8
2. 40 units___16 workers
25 units___x= 10 workers
(25*16)/40=10
3. 40 units___16 workers
100 units___x= 40 workers
(100*16)/40=40
F(g(x)) = [(-7x-8)/(x-1) - 8} / [(-7x - 8)/(x-1) + 7] =
[(-7x - 8 - 8(x-1)) / (x-1)] / [(-7x - 8 + 7(x-1)) / (x-1)] = (-15x) / (-15) = x.
g(f(x)) = [-7*(x-8)/(x+7) - 8] / [(x-8)/(x+7) - 1] =
[(-7x + 56 -8*(x+7)) / (x+7)] / [(x - 8 - (x + 7)) / (x+7)] = (-15x) / (-15) = x.
So since f(g(x)) = g(f(x)) = x we can conclude that f and g are inverses.
