Answer:

La cantidad de dinero

Celia tiene = x = 9.33 €

Quique tiene = y = 4.67 €

Step-by-step explanation:

Representemos la cantidad de dinero

Celia tiene = x

Quique tiene = y

Entre Celia y Quique suman 14 €.

x + y = 14

x = 14 - y

Si Celia tuviera 1 euro, tendría el doble de dinero que Quique.

Por lo tanto,

x = 2 años

Nosotros sustituimos

2y + y = 14

3 años = 14

y = 14/3

y = 4.67 €

x = 14 € - y

x = 14 € - 4.67 €

x = 9.33 €

Por lo tanto,

La cantidad de dinero

Celia tiene = x = 9.33 €

Quique tiene = y = 4.67 €

Which of the following is the solution? A. 2 B. 5≤x<−2 C. 2≤x≤5 D. −5

WARRIOR [948]

Answer:

we conclude that:

$8\le \:-4x$

The graph is also attached below.

Step-by-step explanation:

Given the inequality expression

$9\le 1-4x$

simplify

$9\le -4x+1$

Add -1 to all parts

$9+(-1)\le -4x+1+(-1)$

simplify

$8\le -4x$

Divide all parts by -4

$\frac{8}{-4}\le -\frac{4x}{-4}$

$-2\ge \:x>-5$

Thus, we conclude that:

$8\le \:-4x$

The graph is also attached below.
