Answer:
(a) y=8x-46
(b) 8x-y=46
Step-by-step explanation:
-y=-8x+4
y=8x+4
We know that 8 is the slope, and if we need a equation parallel to this line, then it will have the same slope.
Substitute (6,2)
2=8(6)+b
2=48+b
b=-46
The final answer is y=8x-46
Answer:
a = 8 2/3.
Step-by-step explanation:
The y coordinate of the point is 5, andthe x coordinate is a so substituting for these in the given equation:
3a - 4(5) = 6
3a - 20 = 6
3a = 26
a = 26/3
= 8 2/3

Step-by-step explanation:
The formula for compound interest, including principal sum is:
, where:
- A is the future value of the investment/loan, including interest
- P is the principal investment amount
- r is the annual interest rate (decimal)
- n is the number of times that interest is compounded per unit t
- t is the time the money is invested or borrowed for
∵ Phineas puts $800 into a certificate of deposit
∴ P = 800
∵ The rate of deposit is 3.39%
∴ r = 3.39% = 3.39 ÷ 100 = 0.0339
∵ The money is compounded monthly
∴ n = 12
∵ t = 3
- Substitute these values in the formula above
∴ 
∴ 
∴ A = 885.51407
- Round it to the nearest cent ⇒ hundredths place
∴ A = 885.51
