Answer:
1. The domain of f(x) is (–∞, –5) U (–5, ∞).
4. The y-intercept is (0, 2).
5. There is a vertical asymptote at x = –5.
6. The end behavior is x → –∞, f(x) → 0 and x → ∞, f(x) → 0.

Answer:
38.5 pages
Step-by-step explanation:
11pages:2mins
x pages: 7 mins
you need to divide 7 by 2 and get 3.5, then multiply 3.5 by 11 and receive 38.5
X^4 - x^2 + 9 - (x^3 + 3x^2 + 12) =
x^4 - x^3 - 4x^2 - 3
50 ounces of 15% saline solution contains 0.15*50 = 7.5 ounces of salt.
Let x be the amount of pure water you add to this solution. Then you end up with (x + 50) ounces of this new solution. The amount of salt stays the same.
You want the new solution to have a concentration of 10%. This means you need
7.5 / (x + 50) = 0.1
==> 7.5 = 0.1(x + 50)
==> 7.5 = 0.1x + 5
==> 2.5 = 0.1x
==> 2.5/0.1 = 0.1x/0.1
==> x = 25
<span>assume z = ax for simplicity
z(z) = a(ax) = a^2x
let a^2x = 1/16x and solve for a </span>
