Verify that f and g are inverses functions using composition , show your steps
Answers
Answer: We can conclude that f(x) and g(x) are not inverses.
Step-by-step explanation:
If we have two functions:
f(x) and g(x)
These functions are inverses if:
f( g(x) ) = x
g( f(x) ) = x
In this case, we have:
f(x) = 12*x - 12
g(x) = (1/12)*x - 1
Now we need to check the compositions:
f( g(x) ) = 12*g(x) - 12 = 12*( (1/12)*x - 1) - 12 = (x - 12) - 12 = x - 24
and:
g( f(x)) = (1/12)*f(x) - 1 = (1/12)*(12*x - 12) - 1 = 12*x/12 - 12/12 - 1 = x - 1 - 1 = x - 2
In both cases, we can see that:
f( g(x) ) ≠ x
and:
g( f(x) ) ≠ x
Then we can conclude that f(x) and g(x) are not inverses functions.

Andrew is starting his own snow plowing business. Andrew has calculated that he needs to earn $500 per week to support his family. If he knows he will only be able to work 50 hours per week, what is the minimum amount of dollars per hour that he will need to charge his customers?
Answers
Answer:Ten dollars per hour
Step-by-step explanation:
50 hour =500 dollars
1 hour = ?
Using the criss cross method we multiply one hour by five hundred dollars and divide by fifty dollars.
?=(1 hour×500 dollars)/50 hour
?= 500 dollars/50
?=10 dollars per hour
Answer:
$10
Step-by-step explanation:
$500/50= 10
He needs to earn $10 an hour x the 50 hours = $500
One month Sam rented 3 movies and 8 video games for a total of $55 . The next month he rented 5 movies and 2 video games for a total of $18 . Find the rental cost for each movie and each video game.
Answers
Answer:
Step-by-step explanation:
You are trying to find the values of two quantities, so you will need to set up a system of two equations in two variables. We'll call M the price of a movie and V the price of a video game.
The first month: 3 movies, 8 video games, $55. Let's translate this into algebra:
3M + 8V = 55
The second month: 5 movies, 2 video games, $18. Translated:
5M + 2V = 18
Solve that system of equations

A hula hoop measures 14 inches from the center to the outside. What is the distance around the hula hoop?
A. 21.98 in
B. 175.84 in
C. 43.96 in
D. 87.92 in
Answers
Answer: D. 87.92 in
Step-by-step explanation:
The hula hoop is a circular shape so assume that this is a circle.
The 14 inches that it measure from the center to the outside is therefore the radius.
The distance around the hula hoop being looked for is the circumference.
Circumference of a circle = 2 × π × radius
= 2 * 22/7 * 14
= 88 inches
Closest answer in options is D. 87.92 inches.

An international company has 23,200 employees in one country. If this represents 26.7% of the company's employees, how many employees does it have in total?
Round your answer to the nearest whole number.
Answers
Answer:
Total number of employees = 86,891 employees
Step-by-step explanation:
Let
x = total number of employees
26.7% of x = 23,200
26.7/100 * x = 23,200
0.267 * x = 23,200
0.267x = 23,200
x = 23,200/0.267
x = 86,891.385767790
approximately 86,891 employees
Total number of employees = 86,891 employees

The Grand Old Duke of York had 10 000 men. He lost 10% of them on way to the top of
the hill, and he lost 15% of the rest as he marched them back down the hill.
What percentage of the 10 000 men were still there when they reached the bottom of
the hill?
Answers
Answer:
76.5%
Step-by-step explanation:
He lost 10% of them on way to the top of the hill
10% of 10,000 men
= 0.1 * 10,000
= 1,000 men
Remaining men = 10,000 - 1,000
= 9,000 men
15% of the rest as he marched them back down the hill.
15% of 9,000 men
= 0.15 × 9000
= 1,350 men
Total men remaining = 9000 - 1,350
= 7,650 men
% remaining =
x% of 10000 men = 7,650
x/100 * 10,000 = 7,650
Cross product
10,000x =7,650 * 100
10,000x = 765,000
x = 765,000/10,000
= 76.5%
x = 76.5%

Step-by-step explanation:
The shape is composed of a rectangle and a triangle on the right side
area of rectangle = 15 × 6 = 90 cm²
The triangle has dimensions , base = (15 - 9) = 6 cm and height = (11 - 6) = 5 cm
area of triangle = [tex]\frac{1}{2}[/tex] × 6 × 5 = 3 × 5 = 15 cm²

Students at Garcia Middle School took a survey about their favorite school.The results showed that 182 students rated pizza as their favorite food. This number represented 68% of the number of students who took the survey.What was the total number of students that took the survey?
Answers
Answer:
267.64 students
Step-by-step explanation:
Let the total number of students that took the survey be represented as x
This number represented 68% of the number of students who took the survey.
The results showed that 182 students rated pizza as their favorite food.
Therefore:
68% × x = 182 Students
68/100 × x = 182
68x/100 = 182
Cross Multiply
68x = 182 × 100
x = 182 × 100/68
x= 267.64705882 students
Therefore, the total number of students that took the survey is Approximately 267. 64 students
P and Q form a linear pair if m P=(7x-4) and m Q =(2x-5) find the measure of each angle
Answers
Answer:
Answer:
Angle P = 143º
Angle Q = 37º
Step-by-step explanation:
Linear pair means the angles add up to 180º
So, using this, set up the equation: 7x - 4 + 2x - 5 = 180
Combine Like Terms
9x - 9 = 180
Add on both sides
9x = 189
Divide
189/9 = 21
Substitute 21 for x
Angle P: 7(21) - 4
Angle Q: 2(21) - 5
