Answer:
x=1/5y+−4/5
Step-by-step explanation:
Let's solve for x.
y=5x+4
Step 1: Flip the equation.
5x+4=y
Step 2: Add -4 to both sides.
5x+4+−4=y+−4/5x=y−4
Step 3: Divide both sides by 5.
5x/5=y−4/5x=1'5y+−4'5
Answer:
x=1/5y+−4/5

Answer: I chose question number 1.
2 coconuts= 2 points
1 coconut + 1 apple (10 points) + Banana (4 points)= 15 points.
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:

Test a pair from each table by substituting their values into the given equation and solving.
A) y = 2x + 1 .......... 2 = 2(0) + 1 .......... 2 ≠ 1
B) y = 2x + 1 .......... 1 = 2(0) + 1 .......... 1 = 1
C) y = 2x + 1 .......... -1 = 2(0) + 1 .......... -1 ≠ 1
D) y = 2x + 1 .......... -2 = 2(0) + 1 .......... -2 ≠ 1
The only pair that satisfied the equation was from answer choice B. Therefore, B is the correct answer.
