I think that the right answer for this question is 6
Answer:
third answer
Step-by-step explanation:
The end behavior of the function indicates that the leading coefficient of x is negative (as x approaches infinity, f(x) approaches negative infinity for cubic functions with negative leading coefficients). This eliminates the first 2 answers. Next, factor out the common factor from the 3rd answer and set it to 0 to see if the roots of the polynomial shown on the graph (x=-3, x=2) match that of the answer.
- factor out -2x since each term in the 3rd answer is divisible by -2x => -2x(x^2+x-6)
- set the factored polynomial equal to 0 => -2x(x^2+x-6)
- divide both sides by -2x => 0 = x^2+x-6
- factor => (x+3)(x-2) = 0
- find zeros by setting both factors equal to 0 => x=-3, x=2
This means that the 3rd answer is correct. The last answer, while having the correct leading coefficient, will produce roots of 3 and -2 instead of -3 and 2, which is shown on the graph.

Answer:
First find the 30% of 5-liter cleaning solution.
3/10*5L=1.5L
We know 50% of 3L is 1.5.
If we add, the two bleach percentages, we get 3L of bleach.
When we add the two containers of cleaning solution, we get 8L.
The percentage of bleach in the mixture will be the ratio 3/8 expressed as a %.
3/8*100=37.5% of the cleaning solution will be bleach.
Answer: 37.5%
