</h2>
Step-by-step explanation:
The cost of computer = $ 800
It losed 1/4th of value every year.
The value of computer after 0 years = cost of computer = $ 800
The value after 1 year = 800 - (
) = $600
The value after 2 years = 600 - (
) = $450
The value after 3 years = 450 - (
) = $337.5
The value after n years = computer cost at (n-1) year - ![\frac{1}{4} (n-1 cost)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%28n-1%20cost%29)
Answer:
y=4x+40
Step-by-step explanation:
slope equals 4
x-intercept= -10
y=mx+b for the x-intercept the y equals zero so plugging zero the y and -10 to the x
0=4(-10)+b
0=-40+b now you isolate the variables
b=40 so the equation is y=4x+40 because you have the slope you just pluggin the numbers to the equation
1) 12 cm
2) 38
3) 20
4) 40
Each cm is equivalent to 12.5m. So what you can do I just divide all of them by 12.5 to get the answers above.
