Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Answer:

F. 3/2

Step-by-step explanation:

simplify 12/8

find common factors in 12 and 8

12: 1 , 2, 3, 4, 6, 12

8: 1 , 2, 4, 8

In order to simplify, we need to take the Greatest Common Multiple.

In this scenario it is 4

divide 12 and 8 by 4

You get 3/2

Answer:

the answer is B) logarithmic

Step-by-step explanation:

In the given situation, James wants to find a way to distinguish between a very small intensity, x, and a very large intensity, y. To plot this with most graphs, it would involve using an axis that has a magnitude range of several hundred thousand. However, a logarithmic function allows for a single digit change to represent an increase in magnitude by a factor of ten.

Therefore, the situation is best modeled by a logarithmic function.

Answer:

x = 30°

Step-by-step explanation:

m∠ONK = 180° (straight angle)

∠ONM + ∠MNL + ∠LNK = 180° (supplementary angles)

105° + 45° + m∠LNK = 180° (substitution)

m∠LNK = 30°   (algebra)

m∠LNK + m∠NLK + m∠LKN = 180°   (sum of interior angles of a triangle)

30° + 90° + 2x = 180° (substitution, m∠NLK = 90° bc supplementary angles; other supp. angle is 90°)

120° + 2x = 180°

2x            = 60°

x              = 30°

Answer:

0.80375

because you divide by three

Answer: 2.16

Step-by-step explanation: Just divide 6.48 by 3.

So dividing by 1/2 the same thing as multiplying by the reciprocal. So. I have B 1 plus B 2 equals 2a over H. And I want to solve for B 1 so I just subtract B subscript.

Answer

We can start by calculating the portion of the pizza that Diane ate:

Sully + Wayne + Diane = 1 (since they ate the whole pizza together)

Sully = 0.25 (given)

Wayne = 0.375 (given)

Diane + 0.25 + 0.375 = 1

Diane = 0.375

So Diane ate 37.5% of the pizza, which is the same as Wayne. Now we can calculate the portion that Emma ate:

Sully + Wayne + Diane + Emma = 1

Emma = 1 - Sully - Wayne - Diane

Emma = 1 - 0.25 - 0.375 - 0.375

Emma = 0.0

Since Emma ate all of the remaining pizza, she should pay for the entire pizza. The cost of the pizza is $19.50, so Emma should pay $19.50.

Answer:

The answer is 9.75

Step-by-step explanation:

First, convert the fraction of the pizza that Sully and Diane ate to percents to simplify the calculation.  Next, subtract the percentages of the pizza that Sully, Emma, and Diane ate from 100% to find the percentage of the pizza that Wayne ate.  Finally, multiply the percentage of the pizza that Wayne ate with the cost of the pizza, $19.50, to know, how much he should pay.

Therefore, Wayne should pay $9.75.

Answer:

determine the median of the x-values and the median of the y-values.

Step-by-step explanation:

Answer:

Maybe C because 0 is equal to 0 and 2 is equal to 8 so they are multiplying each number by 4

Answer:

There are two ways to check if 3x+5=11 is true:

Subtract 5 from both sides of the equation. This will isolate x on the left-hand side of the equation.

3x = 6

Divide both sides of the equation by 3. This will divide both sides of the equation by 3, which will cancel out the 3 on the left-hand side of the equation, leaving x by itself.

x = 2

You can also check if 3x+5=11 is true by plugging in 2 for x. If you do this, you will get 3(2)+5 = 6+5 = 11. Therefore, 3x+5=11 is true when x=2.

the answer is 6 because when x=7 on the line it is also equal to 6 on the y axis

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Answer: A: 1/15

Step-by-step explanation:

A number cube has 6 sides.

the probability of getting either a 2 or a 3 will be 2/6, (since both events have an equal chance of happening, and they are out of total 6 possible outcomes).

2/6 simplifies to 1/3, so that is the probability of getting either a 2 or a 3

Next, the probability of landing on blue:

it will be 1/5, since there is only 1 blue section out of 5 *equally* divided sections.

Note that the probability includes the word "and". this means that we will use multiplication.

1/3 * 1/5 = 1/15

and thats the answer!
