Answer:
g(x)= (1/6)x+5/6 is the inverse function of f(x)
Step-by-step explanation:
We have y= 6x-5
Then, we take x depending on y like:
6x-5=y
6x-5 +5 = y + 5
6x= y+5
6x/6=y/6 + 5/6
x= y/6+ 5/6
Now, we replace x by the function g(x) and y by the variable x, then we have
g(x)= (1/6)x+5/6 is the inverse function of f(x).
Hope that you understand.
Alright, this is simple. You know what the new number is, 54. You know the original number was decreased by 40%. Your looking for the original number, X. So set up an equation.
x-.4x=54
When X stands by itself, it's perceived to value 1.00
1.00-.4x=54
(1.00-.4 [40%]=.6)
.6x=54
Divide both sides by .6 to eliminate everything else.
.6x/.6=54/.6
You get 90. Your original number was indeed 90.
To check it, we can do 90/40%, or 90/.4=54

You do 6/4 to find that each friend gets 3/2 or 1.5 apples
Answer:
Step-by-step explanation:
hello :
√(5/4)= √5/ √4 =√5/2 = (1/2)√5
3+√5/4−√5 = 3+(1/2)√5 so : a=3 and b= 1/2
