The answer is that f-1(3) = 7.
In order to find the answer, we first must find the inverse function. The f-1 indicates that we are looking for an inverse. To find any inverse, we first must switch the x and f(x) values. We then solve for the new f(x), which gives us the inverse.
f(x) = (2x - 2)/4 ----> Switch x and f(x)
x = (2f(x) - 2)/4 -----> Multiply both sides by 4
4x = 2f(x) - 2 ----0-> Add 2 to both sides
4x + 2 = 2f(x) ------> Divide both sides by 2
f-1(x) = (4x + 2)/2
Now that we have the inverse function, we can put in 3 and find the answer.
f-1(x) = (4x + 2)/2
f-1(3) = (4(3) + 2)/2
f-1(3) = (12 + 2)/2
f-1(3) = (14)/2
f-1(3) = 7
Answer:
72° = 1.25 radians
Step-by-step explanation:
As we know that,
Thus, 
⇒ 
⇒ 72° = 1.25 radians {∵ Using π = 22÷ 7 or 3.14}
Both degrees and radians are used to measure the angle. They are units of angle.
Answer:
28
Step-by-step explanation:
Draw 7 round cookies and divide each into fourths.
7 cookies cut into fourths groves you 7*4=28 pieces of cookie.
5x + 2y = 13
x + 2y = 9
-------------------------subtract
4x = 4
x = 1
x + 2y = 9
1 + 2y = 9
2y = 8
y = 4
