Answer:x=1
Step-by-step explanation:
The x of the top of the parabola is:
x=-(-8)/(2*4)=1
x=1
I believe its 50 because 0.35x50=17.5 (35%=0.35)
The amount of sugar 
in the starting solution contributes to a 36% concentration, so we have
units of sugar in the solution.
Into this solution, Sharon wants to pour 
liters of water to obtain a smaller concentration of sugar in the overall solution:
So Sharon needs to add 
liters of water to the solution to get the desired concentration.
C(x) = 5x + 2
This is because at 1 hour it only cost 7 dollars, so it should only have 2 added to the end.
Answer:
answer c
Step-by-step explanation:
the two x-intercepts are (-4,0) and (2,0) so the factors of the equation are (x-2) and (x+4). if you multiply the factors it gives you the equation of the graph whic is x^2+2x-8 so c= -8 and b= 2
