Use substitution to solve for x and y.
X=2, y=6
Answer:
Regression lines can be used to predict values within the given set of data, but should not be used to make predictions for values outside the set of data. The correlation coefficient r measures the strength of the linear association between x and y.
Answer:A = $4,066.00
Step-by-step explanation:
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year.
Putting time into years for simplicity,
120 days / 360 days/year = 0.33 years.
Solving our equation:
A = 4000(1 + (0.05 × 0.33)) = 4066
A = $4,066.00
The total amount accrued, principal plus interest, from simple interest on a principal of $4,000.00 at a rate of 5% per year for 0.33 years (120 days) is $4,066.00.

Answer:
an = -39 -100(n -1)
Step-by-step explanation:
The given sequence can be described by a 3rd degree polynomial.* However, we suspect a typo, and that your intention is to have a formula for the arithmetic sequence ...
-39, -139, -239, -339
This has a first term a1 = -39, and a common difference d = -100.
The model for the explicit formula is ...
an = a1 +d(n -1)
Filling in the given values, the formula you seek is ...
an = -39 -100(n -1)
_____
* That polynomial is ...
an = 50n^3 +350n^2 -800n +461
This gives a sequence that starts ...
-39, -139, -139, -339, -1039, -2539, -5139, -9139, ...
