Answer:
First tables blanks are 160, 195, 230, 300
The rate of change would be 35/1 cos the cost is going up by 35 and the months are going up by one
The second tables first row is 1 2 3 4 5, the second row is 5 7 9 11 13
8n−7y−12n+5−3y
=8n+−7y+−12n+5+−3y
Combine Like Terms:
=8n+−7y+−12n+5+−3y
=(8n+−12n)+(−7y+−3y)+(5)
=−4n+−10y+5
I'm pretty sure that this one is the correct factorization of the polynomial above: <span>a) (3x+4)(9x^2-12x+16)</span>
