The inverse function of f(x) = (x + 2)/(x - 3) is given as follows:

[tex]f^{-1}(x) = \frac{3x + 2}{x - 1}[/tex]

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:

[tex]f^{-1}(x) = \frac{3x + 2}{x - 1}[/tex]

Meaning that the fourth option is correct.

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.

The result of the operation is -27 < -18 and the result is true

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

Hence, the result of the operation is -27 < -18 and the result is true

Based on the triangle sum theorem:

20° + (y - 10)° + 4y° = 180

y = 34

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:

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

The difference between depths in January and July is equal to: D. 16 feet.

An absolute value function can be defined as a type of function that consist of an algebraic expression, which placed within absolute value symbols

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.

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)

The quotient of the equation (-y5 - 9y) = y

The term "quotient" is used frequently in mathematics, and it may also refer to a fraction or a ratio as well as the integer portion of a division (in the case of Euclidean division)[2] (in the case of proper division). In the Euclidean division sense, and in the proper division sense, the quotient is "6 with a remainder of 2" when 20 (the dividend) is divided by 3 (the divisor). A quotient in the second meaning is only the proportion of a dividend to its divisor.

According to the given value,

-y*5-9y=y

Mutiply

-5y-9y=y

Combine like terms

-14y=y

Rearrange the terms

-14y -y= O

Combine the terms

-15y =O

divide on both sides

y=o

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)

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)
