Given: <span>f(x) = log3 (x + 1), look for f^-1 (2)
We are looking for the inverse of a function. The inverse of the function can be obtained by switching the variables and obtaining the values of the new function, before substituting f(2). Using a calculator:
</span><span>f^-1 (2) = 8</span>
You have to start by using the distributive property on the left side.
3(2x-7)=5x+4
6x-21=5x+4 Then remove and combine alike terms.
+21 +21
6x=5x+25
-5x -5x
x=25
So to start this off you would add 9y to both sides of the equation and then you regroup it which gives you <span>−2x=−25+9y and then you regroup the terms and get -2x=9y-25 and then you dived both sides by -2 and get x=9y-25/-2 then you simplify and so on
but at the end you should get x=-1 and y =3

The values of x is 1 and 6.
According to the statement
we have two tangents which are represented by x+5 and x+1 then
we have to find the value of x to get the perfect value of tangent
so, due to interior values of tangent they are equal to each other but in opposite sign.
But here we have to find the value of x one by one.
It means
Here we take interior value of tangent and exterior value of tangent equal to each other
So, the equations become are written below
X+5= 6 then x = 1
X+1= 7 then x = 6
So, The values of x is 1 and 6.

Answer:
The second one.
Step-by-step explanation:
Because adding x by anything is 0 since you dont have any other numbers.
