Answer:
Solutions:-5,0,9,6
Not solutions: 12.5,10
Explanation:
The inequality that was given is:
20 > 5 + 3x
First, group similar terms;
20 - 5 < 3x
15 < 3x
x = 5
Thus, the solutions are:-3.5, 5, 4 3/4, -15
The not solutions are:-10 2/3, 129,
Hope this helps! :)
Using an exponential function, it is found that the number 131.5 represents the initial value of the plane, in thousands of dollars.
<h3>Exponential function:</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, the function for the value of the airplane after t years is given by:

Hence A(0) = 131.5, which means that the number 131.5 represents the initial value of the plane, in thousands of dollars.
