The value of y in is 6/7
The equation is given as:
Open the bracket
-3 = 7y - 9
Add 9 to both sides of the equation
7y = 6
Divide both sides by 7
y= 6/7
Hence, the value of y in is 6/7

<h2>Step-by-step explanation:
To find ( f - g)(x) , subtract g(x) from f(x)
That's
Since they have a common denominator that's 3x we can subtract them directly
That's
We have the final answer as

Answer:
See the proof below
Step-by-step explanation:
For this case we need to proof the following identity:
We need to begin with the definition of tangent:
So we can replace into our formula and we got:
(1)
We have the following identities useful for this case:
If we apply the identities into our equation (1) we got:
(2)
Now we can divide the numerator and denominato from expression (2) by and we got this:
And simplifying we got:
And this identity is satisfied for all:
