Which of the following pairs of functions are inverse’s of each other?
liubo4ka [24]

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:

Step-by-step explanation:

SV = RV

2x+2 = 10

x = 4

r² = RV² + VZ² = 10²+7.5² = 156.25

UZ = √[r²- (QR/2)²] = √[156.25 - 10²] = √56.25 = 7.5

Answer:

I believe the correct answer would be A.) Profit.

Step-by-step explanation:

This is because <em>revenue</em> is the amount earned, which, in this case is $100,000. Loss is not a proper term. The proper term would be <em>expense. </em>This is the amount spent or lost. The correct answer would be <em>profit. </em>Profit just means the amount left after the expenses have been deducted from the revenue.

Hope this helps,
