Answer:
The answer is 10a
Step-by-step explanation:
Combine like terms first
a+2a+3a+4a
=(a+2a+3a+4a)
Since all of these numbers have the same variable they can all be added up to get a sum of 10a which is its simplified form.
1) y=Mx+b
2) substitute the values: 0= -8x2 + b
3)multiply: 0= -16 +b
4) add 16 to both sides : 16= b
5) b is your y int. Plug in the values y=2x + 16
Answer : y= 2x+ 16
12
