In other words, find the inverse of the given function f(x).
1. Replace f(x) with "y." y = 8(x+10)
2. Interchange x and y: x = 8(y+10)
3. Solve this for y: y+10 = x/8, or y = x/8 - 10
-1
4. Replace "y" with "f (x) "
-1 x-80
f (x) = ---------- (Answer)
8
Answer:
Step-by-step explanation:
Definitely B. Note how the powers of y are presented in descending order by power: y^8, y^7, y^1.
Answer:
11 miles
Step-by-step explanation:
After the first hour, they walk 3 more hours at 2 miles per hour. So, the total distance is ...
5 mi + (3 h)(2 mi/h) = 5 mi + 6 mi = 11 mi
The blue team will walk 11 miles in 4 hours.
The given question is incomplete. The complete question is:
Omar rented a truck for one day. There was a base fee of $17.95, and there was an additional charge of 98 cents for each mile driven. Omar had to pay $23 when he returned the truck. For how many mile did he drive the truck?
Answer: Omar drove the truck for 5.15 miles
Step-by-step explanation:
Base fee = 17.95 $
Additional charge per mile = 98 cents = 0.98 $ ( 100cents = 1$)
Now Omar payed = 22 $
Let the miles he travelled = x
Now , 
Solvimg for x :

Thus Omar drove the truck for 5.15 miles
