Answer:

No answer

Step-by-step explanation:

Let's say I would like to eliminate x in order to find the value of y.So I multiply the second equation by (-1), but than I also eliminate y. Therefore, this system of equations doesn't have a solution.

A new car is purchased for $47, 000 and over time its value depreciates by one half
andrey2020 [161]

Answer:

$1500

Step-by-step explanation:

you can figure it out by going in increments of 4.5 years because that is the info you have from the problem so

47000 4.5 years later is 23500

9 years = 11750

13.5y = 5875

18y = 2937.5

22.5 years later is 1468.75

22.5 years is about 23 years and to the nearest hundred dollars that is $1500 so that is the answer

Hope this helps! :)
