The line r represents f(x)= x-4/3. therefore, the line that represents f^-1 is and f^-1 (x) =

f^-1 is line P and f^-1 (x) = 3x +4

Step-by-step explanation:

Same reasons as Ikarus

Answer

f^-1(x) = 3x + 4

Step by step explanation

Here we have to find the inverse function of f(x)

f(x) = (x - 4)/3

We can represents f(x) = y

y = (x - 4)/3

To find the inverse function replace "x" by "y" and "y" by "x" as follows

x = (y - 4)/3

Now write the y interms of x.

Multiply by both sides by 3, we get

3x = y - 4

Add 4 on both sides, we get

3x + 4 = y - 4 + 4

3x + 4 = y

Therefore the inverse function f^-1(x) = 3x + 4

Thank you.

The answers would be: x=93 and y=111

To find x, first find the missing angle measure of the triangle: 180-(68+25) = 93
You can then find the measure of x by subtracting 93 from 180.

To find y, find the sum of the missing angle measures in the middle quadrilateral. 360-(66+72) = 222.
Because the missing angle measures are equal to eachother, just divide by 2 to find the angle measure of y.
