Answer:
Basically you first start with having a graph with positive and negative numbers on four sides. Then, you start with 2. You have to graph 2 on the positive y section.
x = 1/1 so you go 1 up which means put another dot at 3 on the y section, then go 1 on the right. And thats it.

Step-by-step explanation:
Answer:
- y = 0.937976x +12.765
- $12,765
- $31,524
- the cost increase each year
Step-by-step explanation:
1. For this sort of question a graphing calculator or spreadsheet are suitable tools. The attached shows the linear regression line to have the equation ...
... y = 0.937976x + 12.765
where x is years since 2000, and y is average tuition cost in thousands.
2. The y-intercept is the year-2000 tuition: $12,765.
3. Evaluating the formula for x=20 gives y ≈ 31.524, so the year-2020 tuition is expected to be $31,524.
4. The slope is the rate of change of tuition with respect to number of years. It is the average increase per year (in thousands). It amounts to about $938 per year.
5. [not a math question]
You can estimate 3.9 times 5.3 to 4 times 5 which is 20
so if the answer is around 20, you know that you will have exactly 2 digits before the decimal place
25:63=25/63=0.39682539682=0.40=40%
Hoped I helped!
The interest on the loan is
.. I = P*r*t = 3000*.09*180/365 = 133.15
Your effective rate is
.. r = I/(Pt) = (100 +133.15)/(3000*180/365) = 15.8%
