8-2(n+3)=n+7-3n
We move all terms to the left:
8-2(n+3)-(n+7-3n)=0
We add all the numbers together, and all the variables
-2(n+3)-(-2n+7)+8=0
We multiply parentheses
-2n-(-2n+7)-6+8=0
We get rid of parentheses
-2n+2n-7-6+8=0
We add all the numbers together, and all the variables
-5!=0
There is no solution for this equation
Yes, the table represents a function.
None of the independent (x) values are repeated and each one has a corresponding (y) value.
If you had a repeated (x) value in the table, it would not represent a function.
Answer: positive
The absolute value of every nonzero integer is a positive integer.
Examples are
|-2| = 2
|7| = 7
The absolute value represents distance which can never be negative. Negative distance does not make sense.
