Which pair shows equivalent expressions?
A.2(2/5x + 2)=2 2/5x + 1
B.2(2/5x + 2)=4/5x + 4
C.2(2/5x + 4)=4/5x + 2
D.2(2/5x + 4)=2 2/5x + 8
Solution:

Let us distribute 2 inside the parenthesis.
That is, we use distributive property:
a(b+c)=ab+ac

So, 
Answer:Option (b)

Applying distributive property, a(b+c)=ab+ac



So, Option (B) is correct.
Answer:
The answer is probably A
Step-by-step explanation:
Its domain is the only one of these that contain -2, which is a real number.
EMERGENCY CORRECTION: THIS IS WRONG AND I'M TOO ST*PID TO FIGURE OUT THE REAL ANSWER I'M SORRY
Answer:
D
Step-by-step explanation:
150-35x=45
X in this equation would be 3
Take 35x3 and you get 105. Plug this in
150-105=45
hope this helps
Answer:
-1
Step-by-step explanation:
slope=(y2-y1)/(x2-x1)=(2-4)/(0+2)=-2/2=-1
C. (8,-2), (-2,5), (6,0) is a function, because all the numbers are different unlike A, B, and D those all have the same number either in there domain or range.
