G((f(x))=1/(1/x)-1
you replace the x in g(x) with f(x).
Answer:
the length of DB is 17 in
Step-by-step explanation:
Consider the sketch attached.
We will draw an imaginary line from point C to met line AB at point E.
A right-angled triangle will now be formed between points CBE.
The dimensions of the right-angled triangle will be:
CB = 10 in
CE= 8 in
EB = unknown
We will now proceed to find out the length of side EB using the Pythagoras' theorem.

From the shape, we can find out that another right-angled triangle is made between points DAB.
The dimensions of the triangle are:
DA= 8in
AB = 9 in + 6 in = 15 in
DB = unknown.
We will now proceed to find out the length of side DB using the Pythagoras' theorem.

Therefore, the length of DB is 17 in

Step-by-step explanation:
The general form of the given equation is 3x-y=0.
The given equation is
.
We need to write the given equation in a general form.
<h3>What is a general form of an equation?</h3>
The general form of any equation contains the degree of variables in decreasing order. The general form of a linear equation is ax + b = 0.
That is, 
.
Hence, the general form of the given equation is 3x-y=0.
