Answer:
i did this 2 months ago, and i believe its A if not sorry
Step-by-step explanation:
4y(3y + 9)
12y + 36
36 ÷ 12=x=3
Find the vertex.
x=b/-2a
12/-2(1)
x=-6
then plug into equation
-6^2+12(-6)+6
36-72+6=-30
(-6,-30)
Answer:
o< 1/16x + 9/16
Step-by-step explanation:
x+9>16o
Flip the equation.
16o<x+9
Divide both sides by 16.
16o/16 < x+9/16
o< 1/16x + 9/16
You would use the POINT SLOPE FORMULA and the Slope Formula
