Answer:

1. 20%

2. 0.37

3. 60%

4. 8 out of 10

5. \frac{5}{6}

Step-by-step explanation:

Percentages are just dividing by 100 because all percentages must equal up to 100 such, as 50% and 50% (50+50=100) or 60% and 40% (60+40=100)

So divide the percentage ( basically just the number not, the %) by 100. 20(%)÷ 100 = 0.2 (take out the % when you do it). 60 ÷ 100 = 0.6

8 out of 10 is 8 ÷ 10 (0.8) if. it was 10 out of 8. it would look like \frac{10}{8}   which you can divide and get 1.2 because the line above the 8 means divide.

and \frac{5}{6} is what i just explained above ↑ divide 5 and 6, which is .83 (it is .8333333333 to infinity and beyond, but I just said 3 because dont  have that line)

now that you have everything in decimals. Sort them!

0.2 (20%)

0.6(60%)

0.37

0.8 (8 out of 10)

5/6 (0.83)

(↑ not the right answer the one in the answer box is.)

What is the inverse of the function f(x) = 2x + 1?
soldier1979 [14.2K]

Answer: The inverse of the linear function f(x)=2x+1 is f^(-1) (x) = (1/2)x-1/2


Solution

f(x)=2x+1

y=f(x)

y=2x+1

Isolating x: Subtracting 1 both sides of the equation:

y-1=2x+1-1

y-1=2x

Multiplying both sides of the equation by 1/2:

(1/2)(y-1)=(1/2)2x

(1/2)y-1/2=x

x=(1/2)y-1/2

Changing "x" by "f^(-1) (x)" and "y" by "x":

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

I don’t know how to do this, please explain :(
IrinaK [193]

Answer:

1. Adjacent and formed a linear pair

2. Adjacent and formed a linear pair

3. Adjacent

4. Not adjacent

Step-by-step explanation:

In essence, adjacent angles are two angles side by side. Two adjacent angles can form a linear pair when they are created by two lines intersecting. So, in broad terms, they are adjacent on a flat plane (or a straight line), and together they make a 180° angle.
