Answer:
Y=2
Step-by-step explanation:
both sides just have to be the same so y-3 is 2x +1
x is -1 so -2 +1=-1 and y-3=-1
Answer:
2468.11 dollars
Step-by-step explanation:
Amount that should be available after four years =3000 $
Interest rate = 5%
No of years =4
Let P be the principal invested
Then ![3000=P(1+0.05)^4\\P=3000(1.05)^{-4} \\=2468.11](https://tex.z-dn.net/?f=3000%3DP%281%2B0.05%29%5E4%5C%5CP%3D3000%281.05%29%5E%7B-4%7D%20%5C%5C%3D2468.11)
Hence 2468.11 dollars should be deposited to get 3000 dollars after 4 years at 5% interest.

Answer:
Step-by-step explanation:
1. Replace F(x) with y.
2. Interchange x and y in y = 2x + 1: x = 2y + 1
3. Solve this result for y: 2y = x - 1, or y = (x - 1)/2
4. Replace y with:
-1
F (x):
-1 x - 1
F (x) = -----------
