Answer:
The value of the car will be x - (0.15)x after a year.
Step-by-step explanation:
The car was 15% more when it first came out, and the price went down by 15% after a year.
Therefore, to solve this problem, we need to multiply 0.15 by the initial cost, which will tell you how much the car price decreased.
Then, we need to subtract this amount from x, or the initial cost, in order to find how much the car will be worth after a year.
Therefore, the value of the car will be x - (0.15)x after a year.

Answer:
Step-by-step explanation:
8y + 11 = 4(y - 2)
8y + 11 = 4y -8
subtract 4y from both sides
4y + 11 = - 8
subtract 11 from both sides
4y = -11
divide by 4 on both sides
y = -2.75 or - y = 2.75
if you need a fraction it would be 2 3/4
