Answer:
y = tan x - pi/2
Step-by-step explanation:
y = arctan(x+pi/2) use that tan y = x is y= arctan x
tan y = x+pi/2; change x with y and find y
tan x= y +pi/2; subtract pi/2 from both sides
-pi/2 + tan x = y
y= tan x -(pi/2) is the inverse function
you can also write it as
y = 1/2(2 tan x -pi)
y = tan x - pi/2

If x = 8, what is the value of 4x + 6?
I NEED HELP! I’m on a test!!
Answer:
=38
Step-by-step explanation:
Use substitution :3
4(8)+6=38
substitute x to 8 then calculate!
There you'll get your answer.
the required value of expression 4x + 6 is 38 when x = 8.
If x = 8, what is the value of 4x + 6 to be determine.
In mathematics, it deals with numbers of operations according to the statements.
The equation is the relationship between variables and is represented as y = 4x +8 is an example of a polynomial equation.
Here, the expression is given as,
y = 4x + 8
now we have x = 8, put this x in y
y = 4(8) + 6
Solving the equation using the PEMDAS rule of mathematics
1St open the parenthesis of 8 then multiply this 8 by 4.
y = 4*8 +6
y = 32 + 6
Now adding 32 and 6 will give 38
y = 38
Thus, the required value of expression 4x + 6 is 38 when x = 8.
