Answer:
Step-by-step explanation:
12) f(x) = 3x
y = 3x
x = 3y
x/3 = y
13) f(x) = 4x-10
y = 4x - 10
x = 4y - 10 (isolate y)
(x+10)/4 = y
The required inverse function would be f⁻¹(x) = x / 3.
What is an inverse function?The inverse function is defined as a function obtained by reversing the given function.
To determine the inverse of a function, all you have to do is switch where x and y are and resolve for y.
We have to find the inverse of the function below :
f(x) = 3x
So after switching x and y,
Now, we solve for y regularly.
f(x) = x = 3y
Solve for y :
⇒ x = 3y
⇒ x / 3 = y
⇒ y = x / 3 = f⁻¹(x)
Therefore, the required inverse function would be f⁻¹(x) = x / 3.

Answer:
not possible
Step-by-step explanation:
Answer:
-17
Step-by-step explanation:
(I originally posted this as a comment because Brainly was not allowing me to answer).
-8 is a negative number, which means many operations don't work the same on it. Subtracting a positive number from a negative number will give you the same result as adding the two positive numbers (in this case, 8 + 9), though the answer will also be negative. Hope this helps!

The circle graph shows the results of a survey. Of those surveyed, 200 said yes. About how many people were surveyed?
Answer:
250 people
Step-by-step explanation:
let's first look for the missing 20%,
one way you can solve this is by cross multiplication:
since 80% is 200 then 80% = 200
and we know 20% is x then 20% = x (we use x because we don't know the amount of people)
so then we set it up:
[tex]\frac{x}{20}[/tex] × [tex]\frac{200}{80}[/tex]
now we cross multiply:
80x = 4000
= x = 50
now we need to find how many people were surveyed so we do:
200 + 50 = 250
250 people were surveyed

Why is y=3 a polynomial function?
Answer: y=3 is a polynomial function? Yes. The equation y=3 represents the function that maps all x values to 3
Step-by-step explanation:
The equation y= 3 represents a horizontal line, which will have exactly one intersection point with any vertical line. So it passes the vertical line test for a function too.

The school that Jenny goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 14 adult tickets and 14 child tickets for a total of $322. The school took in $188 on the second day by selling 12 adult tickets and 1 child ticket. What is the price of each of one adult ticket and one child ticket?A. Adult Tickets: $17, Child Ticket: $12B. Adult Tickets: $15, Child Ticket: $8C. Adult Tickets: $9, Child Ticket: $3D. Adult Tickets: $24, Child Ticket: $13
The price of one adult ticket is $15 and the price of one child ticket is $8.
Two sets of equations can be derived from this question:
14a + 14c = 322 equation 1
12a + c = 188 equation 2
These equations are known as simultaneous equations and they can be solved to determine the cost of each ticket using the elimination method.
In order to determine the cost of the adult's ticket multiply equation 2 by 14
168a + 14c = 2632 equation 3
Subtract equation 1 from 3
2310 = 154a
Divide both sides by 154
a = $15
To determine the cost of the children's ticket substitute for a in equation 1
14(15) + 14c = 322
210 + 14c = 322
322 - 210 = 14c
112 = 14c
c = $8

PROBLEM SOLVING A water sample must be taken from water at least 20 feet deep. Find the depth of the water 50 feet
from shore.
50 ft
5 ft
21.5t
d
Not drawn to scale
The depth is
feet.
Is this an appropriate location for a water sample?
Using the principle of similar triangles, the appropriate depth to take the water sample should be 15 feets
Setting up the equation thus :
1.5 / d = 5 / 50
Cross multiply
1.5 × 50 = d × 5
75 = 5d
Divide both sides by 5
5d / 5 = 75/5
d = 15
Therefore, the appropriate depth to take the water sample is 15 feets.

4. Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the
week beforeThis is a result of...
Sunk cost
Overconfidence
Endowment effect
Answer:
Endowment effect
Step-by-step explanation:
Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the week before.
This is a result of the endowment effect.
Given,
Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the week before.
We need to find whether it is a result of
- Sunk cost
- Overconfidence
- Endowment effect
What are the endowment effect and Sunk cost?
The endowment effect is the effect of placing a higher value on an object
they own than the value on the same object they did not own.
The sunk cost is a cost that has already been incurred and that cannot be
recovered.
We have,
Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the week before.
Here,
We are talking about the same item $20.
Losing $20 is losing what Michael owns.
Finding $20 on the sidewalk is not what Michael owns.
And the pain of losing $20 which he owns is more than the joy of finding it on the sidewalk so,
The Endowment effect is found here.
Thus,
Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the week before.
This is a result of the endowment effect.
