Click the two inequalities represented by the system of inequalities graph below.
1 answer:
The system of inequalities that best represent the shaded feasible region shown on the graph is
- y < x + 1
- y < -x - 2
information gotten from the question include
inequality graph showing shaded regions
some interpretation on the information from the question include
- shading below the is less than
- dotted lines mean the inequality do not have equal to
This interpretation removes the first and the last options since they contain the equal to sign
positive slope moves from bottom left to top right
y < x + 1
negative slope moves from top left to down right
y < -x - 2

Consider the missing part of the question is "Select the correct statement.
A. The number of employees is increasing by 50% every year.
B. The number of employees is decreasing by 10% every year.
C. The number of employees is decreasing by 90% every year.
D. The number of employees is increasing by 90% every year."
Given:
The function is:
Where, f(t) is the number of employees working at a company, in thousands and t is the number of years since the company revised the benefits package.
To find:
The correct statement from the given options.
Solution:
The general exponential decay model is:
...(i)
Where, a is the initial value, r is the rate of decay and t is the number of years.
We have,
It can be written as
...(ii)
From (i) and (ii), we get
The initial value is 1.5 and the rate of decay is 0.10 or 10%. It means the number of employees is decreasing by 10% every year.
Therefore, the correct option is B.
