Answer:

f^-1(x) = 9(x+2)

Step-by-step explanation:

To find the inverse function, exchange x and y and then solve for y

y = 1/9 x -2

Exchange x and y

x = 1/9 y-2

Solve for y

Add 2 to each side

x+2 = 1/9 y-2+2

x+2 = 1/9y

Multiply each side by 9

9(x+2) = 9*1/9y

9(x+2) = y

The inverse function

f^-1(x) = 9(x+2)

Answer:

9x+18

Step-by-step explanation:

f^{-1} means they want you to find the inverse function of y=1/9 x-2.

The inverse is just a swapping of x and y.

People tend to remake the y part the subject again because they want to write it as a function.

Let's start:

y=\frac{1}{9}x-2

Swap x and y:

x=\frac{1}{9}y-2

Now it's time to solve for y:

Add 2 on both sides:

x+2=\frac{1}{9}y

Multiply both sides by 9:

9(x+2)=y

Distribute:

9x+18=y

So The inverse function is:

f^{-1}(x)=9x+18

Solution.

<span>\frac{7}{10} - \frac{3}{10}= The denominators are the same so you subtract the numerator. Your answer should be </span>\frac{4}{10}  simplified your answer is \frac{2}{5}.

Find out the  what percent of people prefer bacon over sausage.

To proof

As given in the question

survey found that 12 out of 30 people preferred bacon over sausage.

Total number of people = 30

people preferred bacon over sausage = 12

Formula

Percentage =\frac{Part}{Total} \times 100

put the value in the formula

Percentage\ of\ prefer\ bacon\ over\ sausage = \frac{12}{30} \times 100

solve the above

percent of people prefer bacon over sausage = 40 %

Hence proved
