O f (x) =
x+10
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.

The sum of two numbers is 26. The first number is two more than 5 times the second number. What are
the two numbers? Define your variables. Write two equations and then solve. Be sure to write your
answer in a complete sentence!
Answer:
Let us assume the two numbers be x and y
From the above condition we can write, x + y = 26 equation 1
second condition first no x = 2 more 5 times of the second no. that is 5y + 2
then we can write, x = 5y + 2..... eqation (2)
from equation 1 x + y = 26
subtracting y from each side , x+ y - y = 26 - y
x = 26 - y
plugging this value of x in eqn. no (2 ) we get,
26-y = 5y + 2
subtracting 5y on both sides,
26 - y - 5y = 5y - 5y + 2
26 - 6y = 2
subtracting 26 from both sides,
26 -26 -6y = 2- 26
-6y = -24
eliminating minus sign from both sides,
6y = 24
dividing by 6 on both sides,
y = 24/6 = 4
substituting this value of y in equation 1 we get,
x + 4 = 26
subtracting 4 from both sides,
x = 26- 4 = 22
Step-by-step explanation:
so we solve the 2 eqns we get x = 22 and y = 4
the two numbers will be 22 and 4

A landfill has 30,000 tons of waste in it. Each month it accumulates an average of 585 more tons of waste. Let m represent the number of months.
What is a function that represents the total amount of waste after m months?
Answer:
f(m) = 585m + 30, 000
Step-by-step explanation:
First you need to set up your variable which is m which makes f(m) and since each month gives 585 tons per month we have the variable attached to that (585m). However, we already start with 30,000 so we add that in. You can check the answer by replacing m with a number, which for me I will choose 10, which gives me 35,850 which makes sense.

Is 2750 a reasonable answer for 917 * 33 explained
Answer:
No
Step-by-step explanation:
To make this simpler, we will round each number. 917 rounds to 900 and 33 rounds to 30. 900 * 30 = 27,000. We can do this in our head because 9 * 3 = 27, and there are three zeros total between 900 and 30, so we add three zeros after 27. 2750 is not a reasonable answer because the true answer is about 10 times greater than 2750.
Question 7 = 2 Points

Samantha has $600 to spend at a bicycle store for some new gear and biking outfits.
Assume all prices listed include tax,
• She buys a new bicycle for $399,95
• She buys 3 bicycle reflectors for $7.01 each and a pair of bike gloves for $34.06.
• She plans to spend some or all of the money she has left to buy new bilding outfits
for $75,88 each
Write and solve an inequality which can be used to determine w, the number of
outfits Samantha can purchase while staying within her budget
Answer:
See belowStep-by-step explanation:
The budget is $600.
Samantha spends the following amount:
399.95 + 3*7.01 + 34.06 = 455.04Now, she plans to buy w outfits which cost $75.88 each.
The inequality for this is:
455.04 + 75.88w ≤ 600Solving this we get:
75.88w ≤ 600 - 455.0475.88w ≤ 144.96w ≤ 144.96 / 75.88w ≤ 1.91w = 1 is the only integer solution greater than zero

What is a clock?A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year.
Now,
Time in Time out
7:05 2:58
7:30 5:01
8:01 4:32
7:22 4:46
6:55 3:31
Between 7:05 and 2:58 the number of hours is 7 hours 53 minutes
Between 7:30 and 5:01 the number of hours is 9 hours 31 minutes
Between 8:01 and 4:32 the number of hours is 8 hours 31 minutes
Between 7:22 and 4:46 the number of hours is 9 hours 24 minutes
Between 6:55 and 3:31 the number of hours is 8 hours 36 minutes
Now, (7+9+8+8+8)+(53+31+31+24+36)
= 40 hours + 175 minutes

Which ordered pair is a solution to the following:
Y= -2x + 5
Choose 1 answer:
A: Only (2,-9)
B: Only (-2,9)
C: both
D: neither
Answer:
Option B: Only (-2, 9)
Step-by-step explanation:
Given the linear equation, y = -2x + 5:
We'll plug in the given options to see which of the ordered pairs will satisfy the equation:
Substitute option A: (2, -9) into the equation:
y = -2x + 5
-9 = -2(2) + 5
-9 = -4 + 5
-9 = 1 (False statement). Therefore, (2, -9) is not a solution.
Substitute option B: (-2, 9) into the equation:
y = -2x + 5
9 = -2(-2) + 5
9 = 4 + 5
9 = 9 (True statement). Therefore, the ordered pair, (-2, 9) is a solution.
The other two options are irrelevant at this point since we've proven that option B is the correct answer.
