F(g(x)) where you see an 'x' in f(x) put a g:

f(g(x)) = 1/(g-7), now step by step: g - 7 = 6/x+7-7=6/x, and 1/(g-7)=1/(6/x)=x/6!

I let the second one for you. Sorry if you disagree!

Suppose PV =NRT, where P=8, V=2X, N=2 and R=2X.you are given X=3. Solve for T
FromTheMoon [43]

Answer:  T = 4

Step-by-step explanation:

1. Write all the variables down

P = 8  V = 2X  N = 2  R = 2X  X = 3

2. Since you know that X = 3 substitute it in to find V and R

V = 2X = 2(3) = 6

R = 2X = 2(3) = 6

3. Find PV

PV = P x V

     = 8 x 6

     = 48

4. Find NRT

NRT = N x R x T

       = 2 x 6 x T

       = 12 x T

       = 12T

5. Find T

PV = NRT

48 = 12T

12T = 48

divide both sides by 12

  T = 48 ÷ 12

  T = 4
