Answer: 
Step-by-step explanation:
We know that the standard quadratic equation is ax^2+bx+c=0
Let's compare all the given equation to it and , find discriminant.
1. a=2, b= -7, c=-9
So it has 2 real number solutions.
2. a=1, b=-4, c=4
So it has only 1 real number solution.
3. a=4, b=-3, c=-1
So it has 2 real number solutions.
4. a=1, b=-2, c=-8
So it has 2 real number solutions.
5. a=3, b=5, c=3
Thus it does not has real solutions.
The ratio of water to sugar would be 4:1 or 4 to 1.
Hope this helps!

Hello from MrBillDoesMath!
Answer:
(g o f)(0) cannot be evaluated
Discussion:
(g o f)(0) = g ( f(0)) if it exists but f(0) is not defined (as division by zero is not defined) so
(g o f)(0) cannot be evaluated
Thank you,
