Answer:
D)-3x+5
Step-by-step explanation:
Hope this helps ;)
Define
v = value after t years.
Therefore the linear model is
v = mt + c
where
m = depreciation rate
t = years since purchase
c = constant
When t=0, v = 20,000, therefore
20000 = m(0) + c
c = 20000
When t=10, v = 2000, therefore
2000 = 10m + 20000
-18000 = 10m
m = -1800
Answer:
The linear model is
v = -1800t + 20000
Answer:
A. their functions in the body

Answer:
x = 45
Step-by-step explanation:
5 (2x - 5) = 1/2 (18x + 40)
10x - 25 = 9x + 20
10x = 9x + 45
x = 45
Guven that the <span>distance
d that a certain particle moves may be calculated from the expression

where a and b are constants; and t is the elapsed time.
Distance is a length and hence the dimension of distance is L.
Now,

and

also will have the dimension of L.
</span><span>Time has a dimension of T.
For

, let the dimension of

be

, then

For

, let the dimension of

be

, then

Therefore, the dimension of

is

while the dimension of

is

.
