Determine by composition whether f(x) = 3x + 18 and g(x)=x-6 are inverses of each other.
O No, f(g(x)) + X
O No, f(g(x)) = x
O Yes, f(g(x)) = g(f(x)) = x
O Yes, f(g(x)) = g(f(x)) * x
Thus, (x) = 3x + 18 and g(x)=x-6 are not inverses of each other.
Two function are inverse if they do undo or cancel each other, which means
f and g are inverse if
f(g(x)) = x and g(f(x)) = x
Here, f(x) = 3x + 18 and g(x)=x-6
Lets check by substituting the values in the formula
⇒ f(g(x))
⇒ f(x-6)
⇒ (3x + 18) - 6
⇒ 3x - 12
⇒ x = 4
g(f(x))
⇒ g(3x + 18)
⇒ 3(x-6) + 18
⇒ 3x - 18 + 18
⇒ 3x
⇒ x = 1/3
What is composition maths?A function is composed in mathematics when two functions, f and g, are used to create a new function, h, such that h(x) = g(f(x)). The function of g is being applied to the function of x, in this case. Therefore, a function is essentially applied to the output of another function.

Stop light A changes color every 45 seconds and Stop light B changes color every 80 seconds. Both Stop lights just changed. After how many seconds will the stoplights change color at the same time?
The stoplights will change color after 720 seconds. at the same time again.
Given: Stoplights A and B alternate between changing colors every 45 and 80 seconds, respectively.
One copy of each of the unique components and the common factor make up the Least Common Multiple (LCM).
The least common multiple of 45 and 80 is the amount of seconds before they change color simultaneously once more.
Since 80 = 5 x 2 x 2 x 2 and 45 = 5 x 3 x 3 respectively
A least common multiple of 45 and 80 is equal to 2x2x2x2x3x3x5 = 720.
Hence, the color of the spotlight will change after 720 seconds. at the same time again.

What time does the shipment arrive in Dallas (GMT -6) , if it departs Edmonton (GMT -7) at 14:45 p.m. on Thursday? United Airlines has a 3 hour 45 minutes flight.
At 17:30 the shipment arrive in Dallas (GMT -6) , if it departs Edmonton (GMT -7) at 14:45 p.m. on Thursday.
The time difference of two zone is -7-(-6) = -1
The shipment departs at 14:45 pm
flight took time = 3:45 min
adding the time = 14:45 + 3:45
= 18:30
So it arrived at Dallas at 18:30 according to Edmonton (GMT -7)
It arrived in Dallas according to Dallas (GMT -6) = 18:30 - 1 hour
= 17:30
What is time zone?
A time zone is a region where everyone adheres to the same standard time for social, business, and legal activities. Because it is simpler for regions that communicate often to maintain the same time, time zones frequently follow national borders and their subdivisions rather than strictly following longitude.
Coordinated Universal Time (UTC), which ranges from UTC12:00 to UTC+14:00, is used to determine all time zones. Most zones have full hour offsets, but some, like those in India, South Australia, and Nepal, have additional offsets of 30 or 45 minutes.

Mel and 5 friends went to the go-kart track. Four people rented helmets for $3 each. The total cost to
rent the helmet and to ride the karts was $75. What was the cost to ride the karts for each person?
The cost of a ride for an individual person will be $10.5
It is given that Mel and 5 friends went to ride which makes the Total number of people for the Ride will be 6. Also, Four of them rented Helmets for the rides each helmet cost $3. It is also given that the total cost of helmets and rides is $75. From this we get :
Total people = 6, Helmet cost = 4*3 = $12, and Total cost = $75
Taking the cost of a ride as 'x' we get the equation representing this statement:
=> 4*3 + 6x = 75 => 6x = 63
=> x = 10.5
We get value of x = $75.
Hence, we get the cost of an individual ride $75.

Jean's bedroom is 12 feet by 10 feet. She has chosen a carpet which costs $30.95 per square yard.
This includes installation.
Answer: i think its 1238 dollars
Step-by-step explanation:
A company makes pencils. they sell each pencil for $10.
Their revenue is represented by R= 10x
The cost to make the pencils is $3 each with a one time start up cost of $5000.
Their cost is represented by C= 3X+5000
1.Find the profit, P, (P=R-C) when the company sells 1000 pens.
2. Find the number of pens they need to sell to break even ( when R=C)
We have the profit fomula:
P = R - C
= $10.x - ($3.x + 1000)
= $7.x - 1000
1. If the company sells 1000 pens:
P = $7 . 1000 - $1000
= $6000
2. If they want to break even:
P at least = 0
Assume P = 0
=> $7.x - $1000 = 0
=> x = 1000/7 ≈ 142,86
So if they want to break even, they have to sell at least 143 pens
Students were asked how they travel to
school. 37% of the students said they
travel by train.
Of these, 24% live more than seven miles
from their school. What percentage of the
students travel over seven miles to school
by train? Give your answer to 2 d.p.
the percentage of the students travel over seven miles to school by train is 9 %.
Let the total number of students be represented by variable x
now, 37 % of them travel by train.
So, we get that:
By train = 37 % of x
By train = 37 / 100 (x)
By train = 0.37 x
Now, 24 % of them lives 7 miles away from the school.
So, 7 miles away = 24 % of 0.37 x
= 24 / 100 ( 0.37 x )
= 0.24 ( 0.37 x)
= 0.09 x
In percentage:
= 9 %
Therefore, we get that, the percentage of the students travel over seven miles to school by train is 9 %.

A salesperson sold a pick-up for $18,760. They were paid a 4.5% commission. How much money were they paid?
the salesperson will be paid $ 844.2 for the one pickup they sell for $ 18,760 as 4.5 % commission is theirs.
We are given that the selling price of a pick up item is given as:
Selling price = $ 18,760
Now, it is also given that, on every sale, the salesperson gain a commission of 4.5 % as their pay.
The money they get paid for one pick up that they sell will be calculated by finding the percentage. So, we get that:
Money = 4.5 % of $ 18,760
Money = 4.5 / 100 × $ 18,760
Money = 0.045 × $ 18,760
Money = $ 844.2
Therefore, we get that, the salesperson will be paid $ 844.2 for the one pickup they sell for $ 18,760 as 4.5 % commission is theirs.

Shinji reads 25 pages of a book every night. 1. Write an equation that represents how many pages Shinji reads (ppp) in some number of nights (nnn).
The equation that represents how many pages Shinji reads is P(n) = 25n
How to write an equation that represents how many pages Shinji reads?The given parameters are:
25 pages = 1 night
Multiply both sides by n
So, we have:
25 * n = 1 * n nights
Express as a function
25 * n = P(n)
Rewrite as
P(n) = 25n
Hence, the equation that represents how many pages Shinji reads is P(n) = 25n
