Answer:

32 - 9 x (don't know what you want simplify or solve for x) x = 32/9

Step-by-step explanation:

Simplify the following:

20 - 3 (3 x - 4)

-3 (3 x - 4) = 12 - 9 x:

12 - 9 x + 20

Grouping like terms, -9 x + 12 + 20 = (20 + 12) - 9 x:

(20 + 12) - 9 x

20 + 12 = 32:

Answer: 32 - 9 x

_________________________________

Solve for x:

20 - 3 (3 x - 4) = 0

-3 (3 x - 4) = 12 - 9 x:

12 - 9 x + 20 = 0

Grouping like terms, -9 x + 12 + 20 = (20 + 12) - 9 x:

(20 + 12) - 9 x = 0

20 + 12 = 32:

32 - 9 x = 0

Subtract 32 from both sides:

(32 - 32) - 9 x = -32

32 - 32 = 0:

-9 x = -32

Divide both sides of -9 x = -32 by -9:

(-9 x)/(-9) = (-32)/(-9)

(-9)/(-9) = 1:

x = (-32)/(-9)

Multiply numerator and denominator of (-32)/(-9) by -1:

Answer: x = 32/9

Miller's Bank is offering a new certificate of deposit (CD) with daily compounding and an annual interest rate of 4.65% for a te

ladessa [460]

Answer:

$20,086.35

Step-by-step explanation:

To calculate the maturity value by compound interest, we will use the formula

$A=P(1+\frac{r}{n})^{nt}$

where,

A = Maturity amount

P = Principal amount = $10,000

r = rate of interest = 4.65% = 0.0465

n = number of compounding periods = 365

t = time in years = 15 years

Now substituting the values,

$A=10,000(1+\frac{0.0465}{365})^{(365)(15)}$

= $10,000(1+0.000127)^{(365)(15)}$

$=10,000(1.000127^{5475})$

= 10,000(2.008635)

= 20086.353758 ≈ $20,086.35

The final value of your investment would be $20,086.35.

NEED HELP!!!!!!

barxatty [35]

1st term = 36
2nd term = 12
3rd term = 4

recursive formula
q = 12/36 = 1/3

If you use this formula and continue going down, you'll eventually find that the 6th term will be 4/27.

Hope that helps!
