Answer:
10 litres of 1% solution and 8 litres of 10% solution
Step-by-step explanation:
Let vol of 1% solution = x
So vol of 10% solution = 18 - x
5% of 18 litres = 0.9
Equation formed is
<h3>x * (1/100) + (18 - x)*(10/100) = 0.9</h3>
x + (18 - x)10 = 0.9 * 100
x + 180 - 10x = 90
-9x = 90 - 180
-9x = -90
x = 10 litres
<h3>10 litres of 1% solution and 8 litres of 10%</h3>

Step-by-step explanation:
Answer:
The zeros are x=-3,-2,1
end behavior is one up one down
Step-by-step explanation:
The zeros are x=-3,-2,1
The end behaviors are one up one down because the function is of degree 3 meaning it is odd function and has opposite end directions.
The answer would be B, because it has a general upward slope
