Answer: A

Step-by-step explanation:

y=2x^2-8

1. Swap x and y.

x=2y^2-8

2. Solve for the new y.

Add 8

x+8=2y^2

Divide by 2.

\frac{x+8}{2}=y^2

Extract the square root.

\sqrt{\frac{x+8}{2} }=y

Savatey [412]
Divide the total portion (9 1/2 cups) by the portion size (3/4 cup).

=9 1/2 ÷ 3/4
convert 9 1/2 to improper fraction

=19/2 ÷ 3/4
to divide fractions, multiply by the reciprocal/inverse of 3/4

=19/2 * 4/3
multiply numerators; multiply denominators

=(19*4)/(2*3)

=76/6

=12.666666


ANSWER: The greatest number he can offer servings to is C) 12

Check the picture below.

since the second figure is also a square, then the sides touching the diagonals have to be all equal, and that'd only happen if those sides bisects the larger square's diagonal.
