The answer is 100X because if you do 5x-4x first it will be 1x. Later on, if you do the exponent you have 1x times 1x. Then you do 1x+9x = 10x
Then you do 10x times 10x because of the exponent is telling you how times you do it and it equals to 100x.
Answer= 100x
I hope this helps YOU!

Answer:
50.2in or 4.2ft
Step-by-step explanation:
This is a problem about proportions so I generally set up my problems like below. I just set some variable here to make it easier to refer back to the measurements for each. You don't have to do this, I am just showing it for clarity. I will convert everything to inches too. We need to find the real window height.
Mb = model building = 18in
Mw= model window = in
Rb = real building = 678ft = 8136in
Rw = real window = ?
=
=
=
=
=
= Rw
= Rw
Rw ≈ 50.2in ≈ 4.2ft
Answer: (x) =
Step-by-step explanation:
f(x) = 9x - 8 , to find the inverse of f(x) , replace f(x) with y , then the equation becomes
y = 9x - 8 , then make x , the subject of the formula ,
9x = y + 8
x =
Finally , replace x , with (x) and y with x , so we have
(x) =
