Step-by-step explanation:
From the question we are told that:
Demand point 
Supply Point 
Generally the equation for fixed-requirement constraints is mathematically given by



Therefore the correct option is
Option B
Answer:
8 - p
Step-by-step explanation:
X is p fewer than Y … X = Y - P
Answer:
1
Step-by-step explanation:
We have the graph of f(x).
In order to find f(0), we simply need to find the y-coordinate of the coordinate when x is 0.
From the graph, we can see that there is a point at (0,1).
In other words, when x is 0, f(x) is 1.
Therefore:

Answer:
; k=25
Step-by-step explanation:

7 less than 25 (or K) is 18.
x = -6, 8
Find the values of x by factoring, getting
(x - 8)(x + 6) = 0
