Answer:
16. $ 4100
17. y = 10000 - 750x
Step-by-step explanation:
16)
As initial value is $ 5000, and salvage value is $ 500. That means in 5 years value decreased by 5000-500 = 4500 so ,
in 5 year value decreased = 4500
in 1 year value decreased = 4500/5 = 900
so per year 900 $ gets decreased from original price. So equation can be given as
V = 5000 - 900y
where V is value of a vehicle and y is number of year
So after 1 year value would be
V = 5000 - 900 x 1 = 5000 -900 = 4100 $
17)
initial cost of car = $ 10000
per year amount decreases by = $ 750
then equation can be given as
y = 10000 - 750x
where x is number of year and y is cost of car after x year.
Answer:
6 without repetition
27 with repetition
Step-by-step explanation:
without repetition, you have 3 digits to choose from initially, then only 2, then only one, i.e.:
3×2×1 = 6
with repetition, you have 3 digits to choose from for every spot:
3×3×3 = 27
Never since they have the same slope so they are considered parallel lines
<span> | 9 - 3g | ≤ 12
This is an example of absolute equality
it could be solved as follows:
9-3g </span>≤ 12 and -(9-3g) <span>≤ 12
</span>
-9+9-3g ≤ 12-9 and -9+9+3g <span>≤ 12+9
</span>
-3g ≤ 3 /-3 and 3g <span>≤ 21 /3
-1 </span>≤ g and g≤ 7
so the interval [-1,7] is the solution to your inequality
hope that helps
Answer:
M/(4+9x)
Step-by-step explanation:
Given equation is M = 4b + 9bx.
M = 4b + 9bx
Factorizing right hand side by b:
b* (4 + 9x)
Reformulating the equation accordingly:
M = b * (4+9x)
Dividing both the left hand side and right hand side of the equation by (4+9x):
M/(4+9x) = b
=> b = M/(4+9x)
Or, In other words the required value of b is M/(4+9x)
This value of b is a function of two given variables,namely M and x, or f(M,x)
