Answer:
25%
Step-by-step explanation:
To solve this, we can use the percent change formula shown in the picture attached below. 
is the new value, 
is the old value, and 
represents the change. For this problem, 80 is the new value and 64 is the old value. Let's plug those numbers into the formula and solve for the percent change:
× 
×
×
Thus, the answer is 25%.

Answer:
It is a function
Step-by-step explanation:
This isn't really a step by step explanation but I'm going to explain this simply. An output can have as many inputs possible but an input can only have ONE OUTPUT(just putting emphasis on this one output, I'm not yelling). Example, the input "2" can be equal to the output of "4" depending on the equation the fuction, however, the input of "2" CAN NOT be equal to the outputs of "4" and "6" because as my Algebra teacher explained it "for every input, there is exactly one output". I hope this helps and I hope I didn't lose you in my explaination.
Rearrange to
6ab+21b-8a-28 now factor 1st and 2nd pair of terms...
3b(2a+7)-4(2a+7)
(3b-4)(2a+7)
So it is the third one down...
