Answer:
Seth's solution is not correct. The x-coordinates are correct, but the y-coordinates are not. The graphs intersect at (-2, -7) and (3, 13).
Step-by-step explanation:
By equating the expressions for y and solving the resulting quadratic, Seth correctly found the x-coordinates of the points of intersection. He needs to compute the corresponding y-coordinates using one or the other of the original equations.
For x=-2,
y = 4·(-2) +1 = -7
For x=3,
y = 4·3 +1 = 13
The points of intersection are (-2, -7) and (3, 13).

Answer:
The principal investment required to get a total amount of $ 1,000,000.00 from compound interest at a rate of 6% per year compounded 12 times per year over 45 years is $ 67,659.17.
Step-by-step explanation:
Given
- Accrued Amount A = $1000000
- Interest rate r = 6% = 0.06
- Time period t = 45 years
- Compounded monthly n = 12
To determine:
- Principle amount P = ?
Using the formula
substituting A = 1000000, r = 0.06, t = 45, and n = 12
$
Therefore, the principal investment required to get a total amount of $ 1,000,000.00 from compound interest at a rate of 6% per year compounded 12 times per year over 45 years is $ 67,659.17.
