a boat costs 11,850 and decreases in value by 10% per year. how much will the boat be worth after 8 years

lawyer [7]

If the boat initially cost $11850 and INCREASED in value by 10% per year, we'd calculate the final value like this:

V = $11850(1+0.10)^8

But if the boat is losing value (depreciating) over time, we'd calculate its final value like this:

V = $11850(1-0.10)^8 = $11850(0.90)^8 = $11850(0.4305) = $5101.04 (answer)

Answer:

x=2

TU:4(2)-1=7

UB: 3

TB: 10

Step-by-step explanation:

4x-1+2x-1=5x

6x-2=5x

6x=5x+2

subtract 5x from both sides

x=2

TU: (4x-1)

4(2)-1

8-1

7

TU:4(2)-1=7

UB: (2x-1)

2(2)-1

4-1

If y varies directly as x and y = 21 when x = 5, find x when y = 42.

Lorico [155]

Answer: 10

<u>Step-by-step explanation:</u>

varies directly means: $\frac{y}{x} = k$

Step 1: solve for k ⇒ $\frac{21}{5} = k$

Step 2: plug in the given value and k to solve for the missing value: $\frac{42}{x} = \frac{21}{5}$

42(5) = 21(x)

$\frac{42(5)}{21} = \frac{21(x)}{21}$

2(5) = x

10 = x
