Answer:

f^{-1}(x)=\frac{1}{4}x+3

Step-by-step explanation:

We have been given the function f(x)=4x-12

Below are steps for finding the inverse of the function.

Step 1:

Replace f(x) with y

y=4x-12

Step 2:

Interchange x and y

x=4y-12

Step 3:

Solve for y

x+12=4y\\\\y=\frac{1}{4}x+3

Step 4:

Replace y with f^{-1}(x)

f^{-1}(x)=\frac{1}{4}x+3

-2x+y=-12, 3y- 2x=-12
inessss [21]

Answer:

x = 6

y = 0

Explanation:

−2x+y=−12;3y−2x=−12

Rewrite equations:

−2x+y=−12;−2x+3y=−12

Solve −2x+y=−12 for y

−2x+y=−12

−2x+y+2x=−12+2x(Add 2x to both sides)

y=2x−12

Substitute 2x−12 for y in −2x+3y=−12

−2x+3y=−12

−2x+3(2x−12)=−12

4x−36=−12 (Simplify both sides of the equation)

4x−36+36=−12+36 (Add 36 to both sides)

4x=24

Divide both sides by 4

4x / 4 = 24 / 4

x = 6

Substitute 6 for x in y=2x−12

y=2x−12

y=(2)(6)−12

y=0 (Simplify both sides of the equation)

A circular racetrack
makkiz [27]
Circle Circumference= 2πr
Diameter is given, but the formula requires the radius.

Radius= diameter ÷ 2= 1/2 ÷ 2= 1/2 * 1/2= 1/4= 0.25

C= circumference
π= 3.14

C= 2πr
substitute in numbers
C= 2(3.14)(.25)
C= 1.57 rounded to 1.6 miles

ANSWER: 1.6 miles

Hope this helps! :)
