2 answers:
Answer:
<em>$32,400 after 12 years</em>
<u>Skills needed: Plugging into Equations</u>
Step-by-step explanation:
1) We need to understand the formula given to us:
,
,
After "x" years, the scholarship has funded y dollars. Whenever we are given x or y we can solve for the other variable given this equation.
2) In the problem, we are given x-value of years (12), and have to find out the y-value from that.
---> Plug in the x-value into the original equation:
->
32400 is your answer.

Answer:
<u>Given</u>
- Equation 5x - y = 12
and
- Inequality 5x - y > 12
<em>See the graphs attached</em>
To draw the graphs follow the rules we described in the previous questions.
- 1. Identify x-intercept and y-intercept and connect them to have the line.
- 2. Shade the region above or below the line for the inequality.
We see the only difference the expressions have is the equation or inequality symbols.
- Equation symbol means the graph of the equation is a line.
- Inequality symbol means the graph of this is a region above the same line, in our case the line is not a part of the covered region because it is "<".
We can state that the inequality excludes the line and includes only the region above the same line.
