Tricky question, but it would be a better deal if he wants extra ribbon, then he could but the 180 inch and get more for only $3.99. But if he wants to have the exact 8 feet ribbon, it would only be $3.12.
Step-by-step explanation:
It is 0.037 so that mean you are right but no right
The answer is the letter C.
Check out desmos, its a great graphing calculator!!
We can start by figuring out the axis of symmetry.
y = x² + 12x = x (x + 12)
So roots are x = -12 or 0
Therefore axis of symmetry is x = (-12 + 0) / 2 = -6
We got x-coordinate of vertex. Now plug in x=-6 to solve for y.
y = (-6)² + 12(-6) = 36 - 72 = -36
Therefore vertex is (-6, -36).
