The least common multiply of 2 and 3 is 6
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:
- temperature is decreasing as time passes
- x-axis
- hot drink temperature (°C)
Step-by-step explanation:
1. Each value of temperature is lower than the one previous, so we can say the temperature is decreasing. We also notice that the rate of decrease is getting smaller, possibly because the temperature is approaching a horizontal asymptote.
__
2. The horizontal axis, where temperature is plotted, is conventionally called the x-axis.
__
3. The label on the vertical axis is "temperature" and the graph title is "cooling a hot drink ...", so we presume the dependent variable is the temperature of a hot drink.

Answer:
(x= -7 , y = -1) is the complete solution of the equation.
Step-by-step explanation:
The given equation is -7x - 5y = 54
Now, here substitute x = -7
So, we get
-7(-7) -5y = 54
or, 49 - 5y = 54
⇒ -5y = 54 - 49
or, -5y = 5
⇒ y = 5/(-5) = -1 , ⇒ y = -1
Hence, (x= -7 , y = -1) is the complete solution of the equation.
