Find the inverse function of f(x)=4x-8

Mathematics
1 answer:
kipiarov [429]3 years ago
8 0

Answer:

f^-1(x)=1/4x+2

Step-by-step explanation:

y=4x-8

change x and y

x=4y=8

switch sides

4y-8=x

add 8

4y=x+8

divide both sides by 4

y=1/4x+2

substitute f^-1(x) for y

f^-1(x)=1/4x+2

9r = 36

9r/9 = 36/9

r = 4cm

if a triangle is an equilateral triangle then the triangle has exactly three 60 angles abc is an equilateral triangle​
Artist 52 [7]

Answer:

The statement is always TRUE

Step-by-step explanation:

An equilateral triangle has all angles and all sides equal

The sum of angles in a triangle is 180 degrees.

Let each of the angles be x degrees.

Then we solve the following equation for x.

x+x+x=180\degree

\implies 3x=180

\implies x=\frac{180}{3}=60\degree
