Find the inverse of f(x)=2x-3.
1) replace "f(x)" with "y." Then y=2x-3.
2) interchange x and y. Then x=2y-3. x+3
3) solve this result for y. Then 2y=x+3, or y=----------------

-1 -1 x+3
4) replace y with f (x): f (x) = ---------

This is the procedure, with the answer given.
Let’s say that Keenan give Tisha 8 of the 16 strawberries he had. So Tisha kept 4 of the 8 strawberries she got from Keenan and gave the rest to Suvi. The expression could be written like this: 16-8=8-4=4
Answer:
speed of the boat = 100 mph
Step-by-step explanation:
Let x = speed of the boat
upstream speed = x - 4
downstream speed = x + 4
time = 24/(x - 4) = 26/(x + 4)
Cross multiply:
24(x + 4) = 26(x - 4)
24x + 96 = 26x - 104
104 + 96 = 26x - 24x
200 = 2x
x = 100 mph
