It wouldbe D.) because you would do
12-4=x
x would be the number of adults
you would solve for x and get 8 so you would have to solve so it would be D.)
Answer:
D) Vertex: (-2,-8); maximum
Step-by-step explanation:
y = -2x² - 8x - 16
The negative on the first term tells us that the vertex will be a maximum
vertex occurs when the derivative is set to zero
y' = -4x - 8
0 = -4x - 8
8 = -4x
x = -2
y = -2(-2)² - 8(-2) - 16
y = -8 + 16 - 16 = -8

36. If 7/11 did bring one, then 4/11 didn't. 4*9=36
Multiply 2 to (4x+3)
8x+6-12=3x-6
bring the x to one side
5x=0
isolate for x
x=0
