The equation to show the depreciation at the end of x years is
[tex]f(x) = 1500 - 200x[/tex]
Data;
cost of machine = 1500annual depreciation value = xLinear EquationThis is an equation written to represent a word problem into mathematical statement and this is easier to solve.
To write a linear depreciation model for this machine would be
For number of years, the cost of the machine would become
[tex]1500 - 200x[/tex]
This is properly written as
[tex]f(x) = 1500 - 200x[/tex]
where x represents the number of years.
For example, after 5 years, the value of the machine would become
[tex]f(x) = 1500 - 200x\\f(5) = 1500 - 200(5)\\f(5) = 1500 - 1000\\f(5) = 500[/tex]
The value of the machine would be $500 at the end of the fifth year.
From the above, the equation to show the depreciation at the end of x years is f(x) = 1500 - 200x

Answer:
(-1,-2) OR x = -1 and y = -2
Step-by-step explanation:
y = 3x + 1
y = -x -3
so you would first multiply everything on y = -x -3 by 3 and get 3y = -3x -9
so then you would add 3y = -3x -9 to y = 3x + 1 ( to eliminate the x )which would be 4y = -8 then divide by 4 and get y = -2
then you plug in y = -2 into any one of the equations but to make it easier i am going to plug it into y = -x -3 so now it would be -2 = -x - 3 then, add 2 to both sides which would be 0 = -x -1 then add 1 to both side 1 = -x then multiply both sides by -1 and get x = -1
SO your answer would be (-1,-2) OR x = -1 and y = -2 ( both of them are correct but it depends on what the teacher taught you)

Jada walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain
empties water from the tank at a constant rate, When Jada first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water.
A. At what rate is the amount of water in the tank changing? Use a signed number, and
include the unit of measurement in your answer.
B. How many more minutes will it take for the tank to drain completely?
C. How many minutes before Jada arrived was the water tank completely full?
Answer:
Part A)The amount of water in the tank is changing at -2/3 gallons per minute.
Part B) it will take 7.5 minutes for the tank to drain completely.
Part C) The water tank was completely full 4.5 minutes before Jada arrived.
Step-by-step explanation:
Information fetching:
Tank of water can hold up-to 10 gallons.
When it is active, a drain empties water from the tank at a constant rate.
7 gallons of water present in the tank when Jade first saw
5 gallons of water left after 3 minutes
Part A) At what rate is the amount of water in the tank changing?
As the gallons were decreased from 7 to 5 in three minutes. It means in three minutes, 2 gallons were decreased.
So, gallons per minute change would be -2/3 gallons per minute. Hence, the amount of water in the tank is changing at -2/3 gallons per minute.
Note: negative sign indicates the number of gallons of water are decreasing.
Part B) How many more minutes will it take for the tank to drain completely.
Let 'm' be the number of minutes will it take for the tank to drain completely.
As,
(2/3 gallons per minute) (m minutes) = 5 gallons
So,
m = 5 (3/2)
= 15/2
= 7.5 minutes
So, it will take 7.5 minutes for the tank to drain completely.
Part C) How many minutes before Jada arrived was the water tank completely full
As tank of water can hold up to 10 gallons. So, the tank of water is full when there is 10 gallons of water. So, this is 3 gallons of water more than the total 7 number of gallons at the time when Jada arrived.
As Jada arrived when the tank had left 7 gallons.
Let 'm' be the number of minutes before Jada arrived when the water tank was completely full.
So,
(2/3) (m) = 3
m = 3(3/2) = 9/2
= 4.5 minutes
So, the water tank was completely full 4.5 minutes before Jada arrived.

A total feet of snow falls over three days. On the first day, 1/6 of the total snow falls. One the second day, 7/12 of the total snow falls. Complete the table to list the amount of snow of snow, in inches, that falls each day. Use paper to show your thinking. Plzzzzzzzzzzzz help plz
Answer:
If it wants to know the total on day 3, then the answer is 3/12, or 1/4 (fully simplified).
Step-by-step explanation:
1/6 + 7/12 = 3/4
This means that you would need 1/4 more inches of snow. 3/12 is the answer before simplification, and 1/4 is the fully simplified answer.

Whats the zeros and the vertex !
Answer:
The vertex is (0,3), and the zeroes are at -1 and -7
Step-by-step explanation:
Since the function is going upward, the vertex is the minimum value
So the vertex is (0,3)
The zeros of a function are where the function touches the x-axis, or when y is 0.
We can find the zeros by making y (or f(x)) 0.
(x+4)^2-9=0
x^2+8x+16-9=0
x^2+8x+7=0
Factoring
(x+1)(x+7)=0
The zeroes are at -1 and -7.

My sister and ate some of a chocolate bar she had 1/4 and I had 5/8 how much of the chocolate bar did we eat
Answer:
7/8
Step-by-step explanation:
1/4 times 2/2 = 2/8. you would have to do this because the only way you can add fractions is if they have the same denominator. so 2/8 + 5/8= 7/8
Answer:
You ate 7/8 of the chocolate bar.
Step-by-step explanation:
First, we need to change 1/4 and 5/8 so that they have the same denominators (bottom numbers).
There's a common multiple of 8.
What you do to the bottom needs to be done to the top.
1 x 8 = 8
1 x 5 = 5
5/8
Your amount of chocolate stays the same.
4 x 2 = 8
1 x 2 = 2
2/8 is how much the sister had,
Finally, add the two fractions together.
2/8 + 5/8 = 7/8
You ate 7/8 of the chocolate bar.
Hope this helps, have a good day! :D
