No, it's a decreasing function
Decide all proper subsets of A { 8 ,7 ,6 ,5 ,4 ,3 ,2 ,1} = A 1- { 4 ,3 ,2 ,1} 2- { } 3- { 9 ,8 ,7 } 4- { 11 ,2} 5- { 5 }

Answer:
A, E
Step-by-step explanation:
There should be 2^8-1 proper subsets of A. Its every one besides { }
Answer:
5
Step-by-step explanation:
4(x+3) is 4x+12
2x+22=4x+12
-2x from both sides
get 22=2x+12
-12 from both sides
get 10=2x
divide by 2 to both sides
get 5
Answer:
x = 6
Step-by-step explanation:
Combine like terms here (anything with the same variable)
5x - 9x = -4x
6-2x = -4x+6
Add the lowest term in both sides
-2x + 4x = 2x
2x - 6 = 6
Add 6 to make 2x alone in order to get x
2x = 12
Divide both of the sides by 2 because that is how you get x all by itself
x = 6
