All functions have an inverse expression.
- The cost function is:
. - The inverse function is:

From the question, we have the following observations:
- Base fare = 50000 pesos for first 100
- Additional guest = 100 pesos
So, the cost function would be:

Where: x represents the number of guests, and C(x) represents the cost function
Expand

Evaluate like terms

To calculate the inverse function, we have:

Replace C(x) with y

Swap x and y

Subtract 40000 from both sides

Divide both sides by 100

Rewrite as:

Split


Hence, the inverse function is:

Answer:
136
Step-by-step explanation:
No matter what the distribution, all of the interior angles of a convex hexagon will add up to 720 degrees. Therefore, if you subtract all of the known angles in this hexagon from 720, you will find x.
720-134-106-117-119-108=136 degrees. Hope this helps!
Answer:
Trinomial.
Step-by-step explanation:
Note how much terms there are in the given expressions:
Term 1: 
Term 2: 
Term 3: 
Note each meaning of the terms:
Monomial: Having only one term.
Binomial: Having two terms.
Trinomial: Having three terms.
Polynomial: Typically used to describe expressions with 4 or more terms.
In this case, there are only 3 terms, and so your answer is Trinomial.

Answer: 1.80
Step-by-step explanation:
Y > -5 is the correct answer.
An open point represents > or <.
The line is to the right, so the symbol is to the left.
