Cara is grocery shopping and needs chicken and steak for the barbecue she is having on saturday. chicken is 2.99 per pound and steak is 5.79 per pound. she knows she wants to spend exactly 50 on meat. if c represents pounds of chicken and s represents pounds of steak, which equation represents this situation

2.99* c+5.79* s= 50

2.99c+ 5.79s =50

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

25.2

step-by-step explanation:

2+4x6-8/10= 25.2
