Answer:

4 (-1 + 2 x)

Step-by-step explanation:

Simplify the following:

9 x - (x + 4)

-(x + 4) = -x - 4:

9 x + -4 - x

Grouping like terms, 9 x - 4 - x = (9 x - x) - 4:

(9 x - x) - 4

9 x - x = 8 x:

8 x - 4

Factor 4 out of 8 x - 4:

Answer: 4 (-1 + 2 x)

Answer:

$\$272,49$

Step-by-step explanation:

7. $\displaystyle /text{The answer makes sense because since the depreciation rate is 15%, we know that we need to use the "exponential decay" formula.}$

6. $\displaystyle /text{After a depreciation rate of 15% for the past 8 years, the stock is now worth approximately $272,49.}$

5. $\displaystyle 1000[0,85]^8 = 272,490525 ≈ \$272,49$

4. $\displaystyle 1000 = a \\ -15\% + 100\% = 1 - r; 85\% = 1 - r \\ 8\:years = time\:[t]$

3. $\displaystyle /text{We need to use the "Exponential Decay" formula} - f(t) = a[1 - r]^t, where a > 0$

2. $\displaystyle /text{How much is the stock worth after a depreciation rate of 15% per year?}$

1. $\displaystyle /text{initial amount: $1000, a depreciation rate of 15%, and a time period of 8 years}$
