Four friends shared 3 orders of chicken wings. • Alex ate 5 of an order. ·8· • Chase ate 7 of an order. ·8· • Ella ate 6 of an order. ·8· How much chicken is left for the fourth friend?

3/4

Step-by-step explanation:

Amount of chicken ordered = 3

Fraction eaten by Alex = 5/8

Fraction eaten by Chase = 7/8

Fraction eaten by Ella = 6/8

The chicken ate by the three friends will be:

= 5/8 + 7/8 + 6/8

= 18/8

= 2 2/8

= 2 1/4

Now, the chicken left for the forty friend will be:

= 3 - 2 1/4

= 3/4

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
