Let the value of the vehicle be described by the equation
V = a + bx
where x = number of years since purchase
a,b are constants.
When x = 0, V = $7500. Therefore
a + b*0 = 7500
a = 7500
When x = 7, V = $500. Therefore
7500 + 7b = 500
7b = 500 -7500 = -7000
b = -7000/7 = -1000
The equation is
V = 7500 - 1000x
The slope of this equation is the depreciation rate, and it is -$1000 per year.
Answer: $1000 depreciation per year.
Answer:
d =2.28 days
Step-by-step explanation:
Given:
V(d) = 350(0.6392)d + 2
Where,
V(d) = number of views
d = number of days
How many days will it take to
reach 100 views?
Find d when V = 100
V(d) = 350(0.6392)d + 2
100 = 350(0.6392)d + 2
100 = 223.72d + 2
100 - 2 = 223.72d
98 = 223.72d
d = 223.72/98
d = 2.2828571428571
Approximately
d =2.28 days
Answer:
10+5x
Step-by-step explanation: First 3x becomes a neggative thus saying there is a minus infront of it then combine the like therms with 8x making it 5x. Once you do that take 7 and add it to 3. Therefore the answer is 5x+10.
Answer:
$20.58
Step-by-step explanation:
28 x 0.30 = 8.4
28 - 8.4 = 19.6
19.6 x 0.05 = 0.98
19.6 + 0.98 = 20.58
