Let me know if you have any questions about any of my work.
Step-by-step explanation:
You are given the following:
and asked to find
.
If you add those because we are asked to find f(x)+g(x) you get:
----------------------------------------------------------
You are given the following:
and asked to find
.
Now this last thing means to replace old input in x^2+3 with new input sqrt(x-2) giving us:
------------------------------------------------------------
We are given
and asked to find g(x) and f(x) such that y=f(g(x)).
We have choices so let's use the choices:
Choice A:
This was actually the desired result.
-----------------------------------------------------------
To find the inverse of f(x)=3x-2 or y=3x-2, your objective is to swap x and y and then remake y the subject.
y=3x-2
Swap x and y:
x=3y-2
Now solve for y.
Add 2 on both sides:
x+2=3y
Divide both sides by 3:
(x+2)/3=y
y=(x+2)/3

a)![x=\dfrac{\text{Total amount}}{\text{Number of tickets}}\\\\x=\dfrac{930.75}{25}](/tpl/images/0094/6964/aa744.png)
b) $37.23
Step-by-step explanation:
Since we have given that
Total amount raised by a theatre company = $930.75
Number of floor seat tickets = 25
We need to find the equation with a variable that can be solved to correctly find the price of each ticket.
Let the price of each ticket be 'x'.
so, Part A becomes,
Part B:
Value of x be
Hence, a)![x=\dfrac{\text{Total amount}}{\text{Number of tickets}}\\\\x=\dfrac{930.75}{25}](/tpl/images/0094/6964/aa744.png)
b) $37.23
