Answer:
Answer
Step-by-step explanation:
0.75x -5 = 0.583333333333...
Answer:
x = 7.4444
Step-by-step explanation:
3/4 x - 5 = 7/12
3x/4 - 5 = 7/12
3x/4 = 7/12 + 5
3x/4 = 7/12 + 60/12
3x/4 = 67/12
3x = 4*67/12
3x = 268/12
3x = 22.3333
x = 22.3333/3
x = 7.4444

A) when f(g(x)) and g(f(x) are inverse functions
B) when f(g(x)) and g(f(x) are equal for at least one value of x
C) when f(g(x)) and g(f(x) are equal for all values of x
D) when f(g(x)) and g(f(x) are not inverse functions
Answer:
The correct option is;
C) When f(g(x)) and g(f(x)) are equal for all values of x
Step-by-step explanation:
To have commutative property is to have the property to move around or change position, as such the commutative property is the property concerns the changing of the positioning of items
The commutative property for addition is a + b = b + a while the commutative property for multiplication is a×b = b×a
For functions , the commutative property can therefore, be expressed as follows;
Commutative property of f(x) and g(x) gives f(g(x)) = g(f(x)) for all values of x.

REALLY IN NEED OF HELP!! please do the best you can<3 Many companies make products to sell, either to other businesses or directly to consumers. The amount of money that a company collects from sales of its products is called its revenue. When a business produces a product, there are costs associated with production. For example, if a cola company is producing a diet cola, they incur costs from purchasing ingredients, aluminum to make cans, cardboard to make boxes, as well as the cost of paying their employees, and more. The profit that a company earns is the difference between the amount earned and the amount spent. Consider the lip color product from each of the two competing high-end cosmetic companies described below. The Alcone Company Besame Beauty This company makes a popular shade of lip color that retails for $45 per tube. The lip color costs The Alcone Company $36 per tube to make and the monthly costs associated with manufacturing just this color are $1,500. A popular shade of lip color from this company costs the consumer $55 per tube. The process to make the lip color costs Besame Beauty $44 per tube and the monthly costs associated with this are $2,200. Use the information given to explore some of the mathematical concepts you have practiced so far by answering the questions below. 1. Develop a single formula you can use to find the profit earned by both The Alcone Company and Besame Beauty for their lip color. Explain why your formula will work for both companies. 2. Write an expression that each company can use to describe the amount of money they will earn from selling their lip colors. Let x represent the number of tubes of lip color each company sells. 3. Write an expression that each company can use to describe the amount of money it costs them to manufacture the lip color each month. Let x represent the number of tubes of lip color each company sells. 4. Use your responses to questions 1, 2, and 3 to write fully simplified expressions each business could use to find their monthly profit. State which property of algebra you are using at each step. Remember that x represents the number of tubes of lip color each company sells. 5. If each company makes 225 tubes of their lip color this month, what amount of profit can they expect? Interpret your answers in terms of the problem’s context. 6. If each company makes and sells 150 tubes of their lip color this month, what amount of profit can they expect? Interpret your answers in terms of the problem’s context. 7. Explain how you used the order of operations to help you answer questions 5 and 6. 8. Explain how you figure out the number of tubes of lip color each company would need to manufacture and sell in order to earn a profit that is greater than 0. 9. Implement your plan from question 8. What is the minimum number of lip color tubes each company would need to manufacture and sell in order to earn a profit that is greater than 0? Interpret your answers in context of the question
Answer:
1. Profit = Revenue - Cost
2. For the Alcone Company Revenue = $45 × x
For the Besame Beauty Revenue = $55 × x
3. Alcone Company; Cost = $1,500 + $36×x
Besame Beauty; Cost = $2,200 + $44×x
4) For Alcone Company, we have;
Profit = $9 × x - $1,500
For Besame Beauty, we have;
Profit = $11 × x - $2,200
5) For Alcone Company;
Profit= $525
For Besame Beauty;
Profit = $275
6) For Alcone Company;
Profit = -$150
For Besame Beauty;
Profit -$550
7) Order of operations is used to ensure that the revenue is first calculated before the cost is subtracted to find the costs
8) In order to find the number of tubes that the company would need to manufacture in order to have a profit of greater than 0, we equate the expression using the inequality of greater than 0 to find the value of x that must be surpassed to have a profit greater than 0
9) For Alcone Company;
The profit will be > 0 at x = 167 tubes
For Besame Beauty;
The profit will be > 0 at x = 201 tubes
Step-by-step explanation:
The given parameters are;
The Alcone Company
The price at which the shade of lip color is sold = $45 per tube
The cost incurred to make the lip color = $36 per tube
The monthly manufacturing cost of manufacturing the lip color = $1,500
For Besame Beauty
The price at which the shade of lip color is sold = $55 per tube
The cost incurred to make the lip color = $44 per tube
The monthly manufacturing cost of manufacturing the lip color = $2,200
1. The formula for finding the profit is given as follows;
Profit = Revenue - Cost
Revenue = Sale price × Number of tubes sold
Cost = The monthly manufacturing cost + The cost incurred to make the lip color × Number of tubes
2. The expression for revenue for the Alcone Company is given as follows;
Revenue = $45 × x
The expression for revenue for the Besame Beauty is given as follows;
Revenue = $55 × x
3. The expression for the cost for the manufacture of the lip color by the Alcone Company per month is given as follows;
Cost = $1,500 + $36×x
The expression for the cost for the manufacture of the lip color by the Besame Beauty per month is given as follows;
Cost = $2,200 + $44×x
4) For Alcone Company, we have;
Revenue = $45 × x
Cost = $1,500 + $36×x
By transitive property and distributive property, we have
Profit = Revenue - Cost = $45 × x - ($1,500 + $36×x) = $9 × x - $1,500
Profit = $9 × x - $1,500
For Besame Beauty, we have;
Revenue = $55 × x
Cost = $2,200 + $44×x
By transitive property and distributive property, we have;
Profit = Revenue - Cost = $55 × x - ($2,200 + $44×x) = $11 × x - $2,200
Profit = $11 × x - $2,200
5) With the number of tubes produced = 225 tubes, we have;
For Alcone Company;
Profit = $9 × x - $1,500 = $9 × 225 - $1,500 = $525
ForBesame Beauty;
Profit = $11 × x - $1,500 = $11 × 225 - $2,200 = $275
6) With the number of tubes produced = 150 tubes, we have;
For Alcone Company;
Profit = $9 × x - $1,500 = $9 × 150 - $1,500 = -$150
For Besame Beauty;
Profit = $11 × x - $2,200 = $11 × 150 - $2,200 = -$550
7) Order of operations is used to ensure that the revenue is first calculated before the cost is subtracted to find the costs
8) In order to find the number of tubes that the company would need to manufacture in order to have a profit of greater than 0, we equate the expression using the inequality of greater than 0 to find the value of x that must be surpassed to have a profit greater than 0
9) For Alcone Company;
Profit = $9 × x - $1,500 >0
$9 × x >0 + $1,500
$9 × x > $1,500
x > $1,500/$9
x > 500/3
x > [tex]166\frac{2}{3}[/tex]
Therefore, the profit will be > 0 at x = 167 tubes
For Besame Beauty;
Profit = $11 × x - $2,200 > 0
$11 × x > 0 + $2,200
$11 × x > $2,200
x > $2,200/$11
x > 200
Therefore, the profit will be > 0 at x = 201 tubes

Answer:
m = -1
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
-13 = 5(1 + 4m) - 2m
Step 2: Parenthesis (distribute)
-13 = 5 + 20m - 2m
Step 3: Combine like terms (m)
-13 = 5 + 18m
Step 4: Subtract 5 on both sides
-18 = 18m
Step 5: Divide both sides by 18
-1 = m
Step 6: Rewrite
m = -1
Answer:
m = -1
Step-by-step explanation:
-13 = 5(1 + 4m) - 2m
Step 1 : Distributive Property
-13 = 5 + 20m - 2m
Add like terms
-13 = 5 + 18m
Subtract 5 on both sides
-18 = 18m
Divide
[tex]\frac{-18}{18}[/tex] = [tex]\frac{18m}{18}[/tex]

Type the correct answer in each box. A company manufactures three types of cabinets, type A, type B, and type C. Last week, the number of type B cabinets produced was 30 more than the number of type A cabinets produced. The number of type C cabinets produced was 20 more than times the number of type A cabinets produced. If the company made the same number of type B and type C cabinets last week, then the number of type A cabinets produced was _____ . The total number of cabinets produced last week was ____.
Hi There!!
B = 1/2A + 30
C = 3/2A + 20
B = C
1/2A + 30 = 3/2A + 20
30 - 20 = 3/2A - 1/2A
10 = A
B = 1/2A + 30
B = 1/2(10) + 30
B = 5 + 30
B = 35
C = 3/2A + 20
C = 3/2(10) + 20
C = 15 + 20
C = 35
type A cabinets produced was 10
type B and type C cabinets produced were both 35

Is the function even or odd?
Answer:
[tex]f(\theta)=\cos(\theta)[/tex] is an even function.
Step-by-step explanation:
Recall when it means when a function is even or odd. An even function has the following property:
[tex]f(-x)=f(x)[/tex]
And an odd function has the following property:
[tex]f(-x)=-f(x)[/tex]
So, let's test some values for cos(x).
Let's use π/3:
[tex]f(\pi/3)=\cos(\pi/3)[/tex]
From the unit circle, was can see that this is 1/2 (refer to the x-coordinate).
Now, let's find -π/3. This is the same as 5π/3. Thus:
[tex]f(-\pi/3)=\cos(-\pi/3)[/tex]
And again from the unit circle, we can see that this is 1/2.
Therefore, despite the negative, the function outputs the same value.
Cosine is an even function.
Notes:
Cosine is an even function and sine is an odd function. It's helpful to remember these as they can help you solve some trig problems!

A 37-ft ladder leans against a building so that the angle between the ground and the ladder is 73°. How high does the ladder reach up the side of the building?
Answer:
35.4 ft
Step-by-step explanation:
To solve this problem, we need to represent the statement in the question in a diagram.
Please see attached photo.
In the attached photo, x is the height of the building.
Thus, we can calculate the value of x as shown below:
Angle θ = 73°
Opposite = x
Hypothenus = 37 ft
Using the Sine ratio, the value of x can be obtained as follow:
Sine θ = Opposite /Hypothenus
Sine 73 = x /37
Cross multiply
x = 37 × Sine 73
x = 35.4 ft
Therefore, the ladder reached up to 35.4 ft of building.
