To explain this clearly, refer to the figure attached. 

Angle addition, from the name itself, is the sum of the smaller angles to make up the bigger angle. In that case, the yellow angle plus the green angle, equals the maroon angle. As long as they have the same vertex (vertex O), you can add up angles that are side by side to obtain the value of the total angle. That is what the phrase <span>"the whole is equal to the sum of its parts" means.</span>

If f(x)=1/9x-2
then f^-1(x) will be
lets assume f(x)=y
y=1/9x-2
y+2=1/9x
9(y+2)=x
f^-1(x)=9(y+2)

a man is 18 years older than his son. 3 years ago he was 4 times as old as his son how old is the man now​
Andru [333]

Answer:

The man is 27 years old.

Step-by-step explanation:

You can create a system of equations.
Let x = the age of the man
Let y = the age of his son
You can create the following equations based on what was given in the problem:
1. x = y + 18
2. (x - 3) = 4(y - 3)
You can simplify the second equation:
x - 3 = 4y - 12
x = 4y - 9
Then, solve the system of equations:
x = y + 18
-
x = 4y - 9
____________
0 = -3x + 27
The son's age is 9, therefore the father is 27 years old.
