The y intercept is -2. There is two x- intercepts because it is a parabola so,
x=-1
x=2
The axis of symmetry is where it splits evenly so, we can conclude it is less than 1 and bigger than 0. I hope this makes sense.
Answer:
1.14 liters
Step-by-step explanation:
We have 8% glycerin solution and we need to make it 16% glycerin solution [more concentration].
When we add "x" liters, we add glycerin as well as changes the total. in 12 Liters, there is 12 * 0.08 = 0.96Liters of glycerin. How much we need to add to this??
Note, 16% = 0.16
We can write a Ratio as shown below, cross multiply and solve for x:

We need to add around 1.14 liters
Put parentheses around the '6 + 12 ÷ 6' and another parentheses around the '6 + 12':-
8 x 5 - ((6 + 12) ÷ 6)
= 40 - (18 ÷ 6)
= 40 - 3
= 37
Cos(39) + x/17
x = 17cos(39)
x = 13.2<span>1148134</span>
