I think the answer Is D fame
The answer is C: 
Starting with the given formula for the area, A = 1/2hb, the first step is to isolate h by using the multiplicative inverse of b, which is
on both sides of the equation:

The result will be:

The last step is to use the multiplicative inverse of
, which is 2 or
to further isolate the variable <em>h </em>:

The formula for h will be:
which is the option C in your question.

Answer:
(x) = 
Step-by-step explanation:
let y = f(x) , then rearrange making x the subject
y = 6x + 7 ( subtract 7 from both sides )
y - 7 = 6x ( divide both sides by 6 )
= x
Change y back into terms of x with x =
(x) , then
(x) =
