y= -3/4x-5/4

3x + 3y = -2
-3x             -3x

3y = -3x-2
/3       /3

y= -1x-2/3

What's the answer? Can't figure it out
soldier1979 [14.2K]
9x⁹ - 90x⁸ - 351x⁷

What do each of these numbers have in common?

They ALL have 9x⁷ in them!

So, divide each one of these by 9x⁷

9x⁹ ÷ 9x⁷ = 9x²

-90x⁸ ÷ 9x⁷ = -9x

-351x⁷ ÷ 9x⁷ = -39

So, factorized completely, it is :

9x² - 9x - 39

~Hope I helped!~
