Replace f(x) with y:
y = 5x-6
Swith the variables:
x = 5y -6
Now solve for y:
add 6 to each side:
x +6 = 5y
Divide both sides by 5:
y = (x+6)/5
Now replace y with the inverse function f^-1 (x):
f^-1(x) = (x+6)/5
3/11
1 - (-2) = 3
4 - (-7) = 11
Here is the work if needed
Answer:
1,140,000,000
Step-by-step explanation:
Answer:
16 folders
Step-by-step explanation:
The first store has 1152 possible combinations. The second store has 72 combinations without the folders.
If we divide 1152 by 72, we have 16. Therefore the second store needs 16 folders to have the same number of combinations as the first store.
