The answers in C are inverses of each other.


In order to find the inverse of any equation, you simply switch the x and f(x) values and then solve for the new f(x). What it will result in is your new inverse function. If we do this for each of the problems above, only one will produce the second equation properly. See the work below for how to do it for C.


f(x) = 11x - 4 ---> Switch the x and f(x)

x = 11f(x) - 4 ----> Add 4 to both sides

x + 4 = 11f(x) ----> Divide both side by 11

\frac{x+4}{11} = f(x) ----> Now put in the correct order

f(x) = \frac{x+4}{11}


Since our inverse matches the g(x) function, this means that C is the correct answer.

Answer:

x = 6

Step-by-step explanation:

First, separate the problem into -\frac{2x}{3} +9=\frac{4x}{3} - 3

Then, Subtract 9 from both sides of the equation. -\frac{2x}{3} +9-9=\frac{4}{3} * x - 3-9

Simplify. -\frac{2x}{3}=\frac{4x}{3}-12

Multiply 3 to each side, which will give you -2x = 4x - 36

Subtract 4x from each side  -2x - 4x = 4x - 36x - 4x

Combine like terms: -6x = -36

Divide both sides by -6

Your answer should be 6

The sum of 4 consecutive numbers is equal to the sum of the next 3 consecutive numbers. Find the largest number.​
timurjin [86]

Answer:

The answer is: The largest number is 15.

Step-by-step explanation:

Let n = the number

n + (n + 1) + (n + 2) + (n + 3) = (n + 4) + (n + 5) + (n + 6)

4n + 6 = 3n + 15

n = 9

Proof:

9 + 10 + 11 + 12 = 19 + 23 = 42

13 + 14 + 15 = 27 + 15 = 42

Hope this helps! Have an Awesome Day!!  :-)
