Answer:
x = 6, y = - 7
Step-by-step explanation:
Given the 2 equations
10x - 3y - 81 = 0 → (1)
- 5x - 7y - 19 = 0 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the x- term
- 10x - 14y - 38 = 0 → (3)
Add (1) and (3) term by term
- 17y - 119 = 0 ( add 119 to both sides )
- 17y = 119 ( divide both sides by - 17 )
y = - 7
Substitute y = - 7 into either of the 2 equations
Substituting y = - 7 into (1)
10x - 3(- 7) - 81 = 0
10x + 21 - 81 = 0, that is
10x - 60 = 0 ( add 60 to both sides )
10x = 60 ( divide both sides by 10 )
x = 6
Answer:
The answer is 2,200.
Step-by-step explanation:
First, you must know by how much the car is depreciating by, in money. Multiply 22,000 by 0.15. That is 3,300. This is how much it depreciates by each year. Now, multiply this by 6 (years) and you get a whopping 19,800! This is how much it has depriciated in 6 years from the original sale. Now subtract 22,000-19,800 and you get 2,200. This is how much the car is worth 6 years from the original sale. So the value of the car is now $2,200. Yikes. Hope this helps!
