Answer:
Los números reales incluyen todos los números racionales, como el entero −5 y la fracción 4/3, y todos los números irracionales, como √2 (1.41421356 ..., la raíz cuadrada de 2, un número algebraico irracional).
Step-by-step explanation:
<span>3x</span>² <span>- 8x -3 = 3x</span>² - 9x + x - 3 =
= 3x² - 9x + x - 3 = 3x* ( x - 3) + 1* (x - 3) =
= 3x * (x - 3) + 1 * (x - 3) = (3x + 1) (x - 3)
Answer (3x + 1) (x - 3)
1.
f(x) = x
g(x) = x + 3
For each x value you use in f(x) and g(x), the corresponding y value in g(x) is always 3 more than in f(x). If each y-coordinate is 3 more, that means the graph is shifted 3 units up. The graph of f(x) is shifted 3 units up to create the graph of g(x).
2.
The first term is -0.5.
Then each term goes up by 0.25.
1st term: -0.5
2nd term: -0.5 + 0.25 = -0.5 + 0.25(1)
3rd term: -0.5 + 0.25 + 0.25 = -0.5 + 0.25(2)
4th term: -0.5 + 0.25 + 0.25 + 0.25 = -0.5 + 0.25(3)
nth term: -0.5 + 0.25(n - 1)
-0.5 + 0.25(n - 1) = -0.5 + 0.25n - 0.25 = -0.75 + 0.25n = 0.25n - 0.75

The questions asks about Combinations of Pizza toppings, so by employing the Combination Formula:
![C(n, k) = \frac{n!}{k!(n-k)!}](https://tex.z-dn.net/?f=C%28n%2C%20k%29%20%3D%20%5Cfrac%7Bn%21%7D%7Bk%21%28n-k%29%21%7D)
![C(6, 3) = \frac{6!}{3! \cdot 3!} = \frac{6 \cdot 5 \cdot 4 \cdot 3 \cdot 2}{3 \cdot 2 \cdot 3 \cdot 2} = 20](https://tex.z-dn.net/?f=C%286%2C%203%29%20%3D%20%5Cfrac%7B6%21%7D%7B3%21%20%5Ccdot%203%21%7D%20%3D%20%5Cfrac%7B6%20%5Ccdot%205%20%5Ccdot%204%20%5Ccdot%203%20%5Ccdot%202%7D%7B3%20%5Ccdot%202%20%5Ccdot%203%20%5Ccdot%202%7D%20%3D%2020)
