Bryan is asked to write an inequality to represent the graph
2 answers:
<h2>Answer:</h2>
The error that Bryan made was:
- Bryan included -14 in his solution set.
The graph is a number line such that the shaded region is to the right of -14.
This means that all the real values which are greater than -14 are in the solution set.
Also, there is a open circle at -1.
This means that -14 is excluded from the solution set.
That is the solution set must contain all the values which are strictly greater than -14
Hence, the inequality has to be strict.
The correct inequality must be:

We have been given that Bobby's investment of $225,000 loses value at a rate of 3% per year. We are asked to find the value of the investment after 10 years.
We will us exponential decay function to solve our given problem.
We know that an exponential function is in form , where,
y = Final amount,
a = Initial amount,
r = Decay rate in decimal form,
x = Time.
Let us convert 3% into decimal.
Upon substituting ,
and
, we will get:
Upon rounding to nearest dollar, we will get;
Therefore, the value of the investment after 10 years would be .
