which function below is the Inverse of f(x)= 7x-1/2
Answer:
[tex]f-1(x)= \frac{x}{7} +\frac{1}{14}[/tex]
Step-by-step explanation:
If we have y=7x-1/2, the inverse is where we solve for x instead of y.
We can isolate x to get 7x=y+1/2, then divide by 7 to get x=y/7+1/14.
Therefore,[tex]f-1(x)= \frac{x}{7} +\frac{1}{14}[/tex]

PLEASE HURRY I ONLY HAVE 5MIN TO TURN IT IN!!! A new television set was recently purchased for a common Room and a resident Hall for $446.90 including tax. If the tax rate is 9%, find the price of the television set before taxes.
Answer:
The price of the tv before tax is 410
Step-by-step explanation:
Let x = price of tv before tax
tax = x* 9%
tax = .09x
The total cost is price of tv before tax plus tax
total cost = x + .09x
total cost = 1.09x
446.90 = 1.09x
Divide each side by 1.09
446.90/1.09 = 1.09x/1.09
410 = x
The price of the tv before tax is 410

The solution is____
Answer:
x > 1
interval (1,∞)
Step-by-step explanation:
1/2(-2x - 12) > 7(3 - 4x)
-x - 6 > 21 - 28x
-x + 28x > 21 + 6
27 x > 27
x > 27 / 27
x > 1
interval (1,∞)
-x - 6 > 21 - 28x if x = 2

Find each of the following functions and state their domains. (Enter the domains in interval notation.)
f(x) = x3 + 4x2, g(x) = 5x2 − 1
(a) f + g
f + g =
domain =
(b) f - g
f − g =
domain =
(c) fg
fg =
domain =
(d) f/g
f/g =
domain =
Answer:
Step-by-step explanation:
Given functions are,
f(x) = x³ + 4x²
g(x) = 5x² - 1
(a). (f + g)(x) = f(x) + g(x)
= x³ + 4x² + 5x² - 1
= x³ + 9x² - 1
Since the composite function is defined for all values of x, domain of the function will be (-∞, ∞)
(b). (f - g)(x) = x³ + 4x² - (5x² - 1)
= x³ - x² + 1
Domain of the function : (-∞, ∞)
(c). (f.g)(x) = f(x) × g(x)
= (x³ + 4x²)(5x² - 1)
= 5x⁵+ 20x⁴ - x³ - 4x²
Domain of the function will be (-∞, ∞).
(d). [tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]
= [tex]\frac{x^3+4x^2}{5x^2-1}[/tex]
Since this function is not defined at [5x² - 1 = 0] Or x = ±[tex]\frac{1}{\sqrt{5}}[/tex]
Therefore, Domain of the composite function will be,
(-∞, -[tex]\frac{1}{\sqrt{5}}[/tex]) ∪ [tex](-\frac{1}{\sqrt{5}},\frac{1}{\sqrt{5}})[/tex] ∪ ([tex]\frac{1}{\sqrt{5}}[/tex], ∞)

I NEED HELP Are the two functions inverses? f ( x ) = − 8 x + 5 g ( x ) = − 1 8 x + 5 8 Group of answer choices Yes No
Answer: No
Step-by-step explanation:
To know if the functions are inverses of each other, it is easiest to just find the inverse of one of the functions. To find the inverse, you want to replace y with x and x with y and solve for y.
y=-8x+5 [switch x with y and y with x]
x=-8y+5 [subtract both sides by 5]
x-5=-8y [divide both sides by -8]
y=(x-5)/-8
f⁻¹(x)=(x-5)/-8
Since we know that the inverse doesn't match g(x), we know that these functions are not inverses of each other.

The cost in dollars of making x items is given by the function C(x)=10x+800. a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item. Fixed cost =$ Number b. What is the cost of making 25 items? C(25)=$ Number c. Suppose the maximum cost allowed is $2300. What are the domain and range of the cost function, C(x)? When you enter a number in your answer, do not enter any commas in that number. In other words if you want to enter one thousand, then type in 1000 and not 1,000. It's not possible to understand what the interval (1,000,2,000) means, so you should write that as (1000,2000). Domain: Preview Range: Preview
Answer:
1. Fixed cost is $800
2.Cost of 25 bags is $1025
3. (170,2300)
Step-by-step explanation:
Given
[tex]c(x) = 10x + 800[/tex]
Solving (a): Fixed cost
From the question, fixed cost is when x = 0;
Substitute 0 for x in [tex]c(x) = 10x + 800[/tex]
[tex]c(0) = 10 * 0 + 800[/tex]
[tex]c(0) = 0 + 800[/tex]
[tex]c(0) = 800[/tex]
Hence, the fixed cost is $800
Solving (b): Cost of making 25 items
Here; x = 25
Substitute 25 for x in [tex]c(x) = 10x + 800[/tex]
[tex]c(25) = 10 * 25 + 800[/tex]
[tex]c(25) = 250 + 800[/tex]
[tex]c(25) = 1025[/tex]
Hence, the cost of 25 bags is $1025
Solving (c): Domain and Range where Maximum cost = $2300
Here; c(x) = 2500
Substitute 25 for c(x) in [tex]c(x) = 10x + 800[/tex]
[tex]2500 = 10x + 800[/tex]
Subtract 800 from both sides
[tex]10x = 2500 - 800[/tex]
[tex]10x = 1700[/tex]
Divide both sides by 10
[tex]x = 170[/tex]
The domain and range of a function is in form of (x,c(x))
Hence, the domain and range is (170,2300)

Lee spent $29 to purchase a combination of drinks, sandwiches, and chips for himself and his friends. A drink costs $1.50, a sandwich costs $5, and chips cost $1.25. Identify the linear equation that represents this situation.
Answer:
1.5d+5s+1.25c=29
Step-by-step explanation:
let d be the number of drinks, s be the number of sandwich, and c be the number of chips Lee purchased.
1.5×d and 5×s and 1.25×c must total 29, or
1.5d+5s+1.25c=29.

Determine the rate of change for 3/2x -5/4y = 15
Answer:
-6/5
Step-by-step explanation:
3/2x - 5/4y = 15
-5/4y = -3/2x + 15
multiply each side by (-4/5)
(-4/5)(-5/4y) = (-4/5)(-3/2x + 15)
y = -6/5x - 12
rate of change: -6/5
Find the quotient for 12 ÷ (-4).

Complete the equation involving x. Order terms like the physical situation, and don't simplify. A 6 foot wide painting should be centered on a 10 foot wide wall. How many feet (x) should be on each side of the painting?
Answer:
The space on each side of the painting = 2 feet
Step-by-step explanation:
Attached this answer is a diagram to give you visuals on how the value of x is calculated
Given:
width of wall = 10 feet
width of painting = 6 feet
Since the painting is centred on a wall, there is meant to be an equal space on each side of the painting, from the diagram, the following eaquation can be gotten
x + 6 + x = 10
2x + 6 = 10
2x = 10 - 6
2x = 4
x = 4 ÷2
x = 2 feet
Therefore, the space on each side of the painting = 2 feet

A spinner had 5 equal sections, labeled A through E. After 100 spins, the spinner had landed on section A a total of 45 times.
On 0.05 percentage of the spins did the spinner land on 2, according to the question.
How do you calculate the value?For spins using the spinner geometry: Shape. Spinners are in the same category as dice. Spinners, in essence, give unpredictability to the creation of numbers, colors, or objects. It can be used in place of dice and vice versa to create numbers. IT may be used in a gaming scenario in the same manner that dice can be used to produce movements.
In 100 Spins it lands on 2 a total of 5 times
Therefore, it’s 5/100×100%
= 5%
So, the Answer is 5. So 5% .
To convert a percentage to a decimal, divide by 100. So 5% is 5/100, or 0.05. To convert a decimal to a percentage, multiply by 100 , move the decimal point 2 places to the right.

Write 6.93 repeating a mixed number in simplest form.
6.93 =?
Answer:
[tex]6\frac{93}{100} = \frac{693}{100}[/tex]
Step-by-step explanation:
Turn 6.93 into a fraction: [tex]6\frac{93}{100}[/tex] To turn into a mixed number, first multiply 6 and 100, then add 93. Put 693 over 100: [tex]\frac{693}{100}[/tex]I hope this helps!
Answer: [tex]6 \frac{31}{33}[/tex]
This is a mixed number where the whole part is 6, and the fractional part is 31/33.
=============================================
Explanation:
The 93 repeats forever, so we can say
x = 6.939393...
100x = 693.939393....
Subtracting the left hand sides leads to 100x-x = 99x
Subtracting the right hand sides leads to 693.939393.... - 6.939393... = 687
Notice how the decimal terms cancel out when we subtract.
We're left with 99x = 687 which solves to x = 687/99
This reduces to 229/33 when you divide both parts by 3.
The last step is to convert to a mixed number
The answer will be in the form [tex]6 \frac{x}{33}[/tex] where 6 is the whole part and x/33 is the fractional part. We know the whole part is 6 from the 6 in the original number given.
229/33 = 6.939393... helps confirm we're on the right track so far
this is another way of saying 229/33 = 6 remainder x, where x is the unknown remainder and the numerator we're after for the fraction x/33.
To get the remainder, we just compute 229-6*33 to get 31
This means 31/33 = 0.93939393...
and that [tex]6 \frac{31}{33} = 6.\overline{93} = 6.93939393...[/tex]

Write each statement as a decimal to two decimal places. $6.00 to 95 cents = 3 hours to 35 minutes = 42 inches to 2 feet = (Hint: there are 12 inches in 1 foot.)
Answer/Step-by-step Explanation:
The above given statements can be written as decimals by first writing both quantities in a statement in the same unit.
1. $6.00 to 95 cents:
This is same as $6.00 : 95 cents = [tex] \frac{6.00}{95} [/tex]
Convert $6 .00 to cents to make both quantities be in the same unit.
$1 = 100 cents
$6.00 = 6*100 = 600 cents
[tex] \frac{600}{95} = 6.32 [/tex] (to 2 d.p)
2. 3 hours to 35 minutes:
Convert 3 hours to 35 mins
1 hr = 60 mins
3 hrs = 3*60 = 180 mins
[tex] 180mins : 35 mins = \frac{180}{35} = 5.14 [/tex] (2 d.p)
3. 42 inches to 2 feet:
Convert 2 ft to inches
1 ft = 12 inches
2ft = 2*12 = 24 inches
[tex] 42 in:24 in = \frac{42}{24} = 1.75 [/tex]
