Step-by-step explanation:

x = ounces of 20% solution

15% = 0.15

20% = 0.2

17% = 0.17

x × 0.15 + 8×0.2 = (8 + x)×0.17

x×0.15 + 8×0.2 = 8×0.17 + x×0.17

8×0.2 = 8×0.17 + x×0.02

8×0.03 = x×0.02

x = 8×0.03/0.02 = 12 ounces

we need to mix the 8 ounces of 20% with 12 ounces of 15% to get 17% alcohol (8 + 12 = 20 ounces of it).

Answer:

A

Step-by-step explanation:

-5x + 10 > -15

-5x > -25

x < 5

(switch direction of inequality sign when multiplying or dividing by a negative number)

Because x < 5, the arrow would go left (more negative) starting at 5, so the answer would be A.

Answer:

<em> f ( x ) = - 2x^2 + 3x + 1</em>

Step-by-step explanation:

If f ( x ) extends to → − ∞, as x→ − ∞ , provided f(x) → − ∞, as x → +∞, we can rewrite this representation as such;

− ∞  < x < ∞, while y > − ∞

Now the simplest representation of this parabola is f ( x ) = - x^2, provided it is a down - facing parabola;

If we are considering a down - facing parabola, the degree of this trinomial we should create should be even, the LCM being negative. Knowing that we can consider this equation;

<em>Solution; f ( x ) = - 2x^2 + 3x + 1</em>, where the degree is 2, the LCM ⇒ - 2
