The bowling alley charges $8 per person for a bowling party, and they accept parties of 8 to 40
people. Write the equation that best fits the situation. Write the reasonable Domain and Range for the
situation.
The reasonable Domain and Range for the situation.
The Domain of this situation is y ≥ 64 and the Range is 8≤ x ≤40Given that
The bowling alley charges $8 per person for a bowling party.they accept parties of 8 to 40 peoples.To find
he reasonable Domain and Range for the situation.So, according to the question
We have,
The bowling alley charges per person = $8.They just accept parties of 8 to 40 peoples.So, we can say that
Total charges = 8 (total number of peoples in a party)
Let's assume
Total charges = y , and
Total number of peoples in a party = x
Then, we get a equation of this problem,
y = 8x ------------(1)
So, the domain of this equation will be greater then and equal to 64. and range will be greater then and equal to 8 and less then and equal to 40.

Tau says that the
sum of -1 3/4 and 2 1/2 is the same as the difference
between 2 1/2 and 1 3/4. Is Tau correct? Explain why
or why not.
Tau is correct, the sum between -(1 ³/₄) and (2 ¹/₂) is equal to the difference between (2 ¹/₂) and (1 ³/₄)
Is Tau correct?
Remember that the sum between a number A and a negative number -B is written as:
A + (-B)
And that is equal to the difference between A and B.
A - B
In this case, Tau says that the sum between:
-(1 ³/₄) and (2 ¹/₂)
Is written as:
(2 ¹/₂) + (-(1 ³/₄) )
(2 ¹/₂) - (1 ³/₄)
And, using the above property, we conclude that this is equal to the difference between (2 ¹/₂) and (1 ³/₄)
So Tau is correct.

What is an absolute value function?An absolute value function can be defined as a type of function that consist of an algebraic expression, which placed within absolute value symbols
How to determine the difference between depths?In order to determine the difference between depths, we would calculate the magnitude of the depth for each of the month.
For January, we have:
January depth = 20 - 6
January depth = 14 feet.
For July, we have:
July depth = 20 - 22
July depth = -2 feet.
Now, we can calculate the difference between depths in January and July:
Difference = 14 - (-2)
Difference = 14 + 2
Difference = 16 feet.

Use the equation to justify your answer.
$20+\left(y-10\right)+4y=$

Based on the triangle sum theorem:
20° + (y - 10)° + 4y° = 180
y = 34
What is the Triangle Sum Theorem?The triangle sum theorem states that if we add up all the three interior angles in a triangle, the sum we would get would be equal to 180 degrees.
Given the following are interior angles of a triangle:
4y°(y - 10)°20°Based on the triangle sum theorem, we have the following equation:
20° + (y - 10)° + 4y° = 180
Solve for y
20 + y - 10 + 4y = 180
10 + 5y = 180
5y = 180 - 10
5y = 170
5y/5 = 170/5

The inequality -15 <-6 is given. Perform the given operation, then write a true
inequality to match the result.
Subtract 12 from both sides of the inequality.
The result of the operation is -27 < -18 and the result is true
How to perform the operation on the inequality expression?The inequality expression is given as:
-15 < -6
The operation on the inequality expression is given as:
Subtract 12 from both sides of the inequality.
So, we start by subtracting 12 from both sides of the above inequality
This is represented as
-15 - 12 < -6 - 12
Evaluate the difference
So, we have
-27 < -18
The above inequality is true because -27 is less than -18

f inverse of x is equal to the quantity 3 times x plus 2 end quantity over the quantity x minus 1 end quantity
The inverse function of f(x) = (x + 2)/(x - 3) is given as follows:
[tex]f^{-1}(x) = \frac{3x + 2}{x - 1}[/tex]
How to obtain the inverse function?The function in this problem is defined as follows:
f(x) = (x + 2)/(x - 3).
Using the notation y = f(x), it is given as follows:
y = (x + 2)/(x - 3).
To obtain the inverse, the first step is exchanging the variables x and y, as follows:
x = (y + 2)/(y - 3).
Now the variable y must be isolated to obtain the inverse function, as follows:
xy - 3x = y + 2
xy - y = 3x + 2
y(x - 1) = 3x + 2
y = (3x + 2)/(x - 1).
Hence the inverse function is given by:

The length of the enclosure for the pancake tortoise must be greater than the height. The volume of the enclosure is expressed in terms of the width, w.
w^3+6w^2-40w
Factor the expression, then match the factors to the dimensions they represent.
The factors of the expression w³ + 6w² - 40w = 0 is (w - 4) and (w + 10)
(w - 4) will be the height
(w + 10) will be the length
Given,
The length of the enclosure for the pancake tortoise will be greater than the height, that is: l > h
The volume of enclosure = w³ + 6w² - 40w
Where w is the width.
Now, factorize the expression:
w³ + 6w² - 40w = 0
10 - 4 = 6
10 × (-4) = -40
Therefore, the factors of the expression w³ + 6w² - 40w = 0 is (w - 4) and (w + 10)
Here, we know that length is greater than height.
So, (w - 4) will be the height and (w + 10) will be the length.

A rental car agency charges $180 per week plus $0.25 per mile to rent a car. How many miles can you travel in one week for $382.50?
Answer:
810
Step-by-step explanation:
382.50-180= 202.5
202.5 / 0.25= 810
Hope this helps!
Answer:
810 miles
Step-by-step explanation:
$180 a week is the fixed cost so we subtract this first.
($382.50 - $180 = $202.50)
The number left is the amount of dollars charged per mile.
So if we divide this number by $0.25, we get how many miles travelled.
($202.50 ÷ $0.25 = 810 miles)
