First find x in terms of f(x)
1/2 x = f(x) + 4
x = 2(f(x) +4)
x = 2f(x) + 8
Now replace x by the inverse function f-1(x) and the f(x) by x
f-1(x) = 2x + 8
f-1 (4) = 2(4) + 8 = 16
Given the numbers above and those numbers only the mean would be 1.8
Answer:x= 36 y= 67 and z=77
Step-by-step explanation: we have to write the equations from the data give in the exercise, this means :
First of all, x,y and z correspònd to the first, second and third angles, respectively.
The sum of the measures of the angles of a triangle is 180
can be written as x+y+z=180
The sum of the measures of the second and third angles is four times the measure of the first angle.
It can be written by: x+y=4z
The third angle is 10 more than the second
It can be written as z=y+10
By solving the equations systems the above values can be determined.
x+y+z=180
x+y=4z
z=y+10
A = 3.125
Sorry I only know A.
You would divide 500 by 160.
