Vika [28.1K]3 years ago
8 0

Answer:

See below.

Step-by-step explanation:

Substitute the values for x.

h(-5) = 4(-5) - 5 = -25

h(-1) = 4(-1) - 5 = -9

h(2) = 4(2) - 5 = 3

h(3) = 4(3) - 5 = 7

h(5) = 4(5) - 5 = 15

La edad de Ericka es el tripl de la edad de Liliana y hace 9 años la suma de sus edades era 22. ¿Cuantos años tiene actualmente
Gnom [1K]

Answer:

Liliana tiene 10 años.

Step-by-step explanation:

Definamos las variables:

E = edad de Ericka

L = edad de Liliana.

Primero sabemos que la edad de Ericka es el triple de la edad de Liliana, entonces:

E = 3*L

Tambien sabemos que hace 9 años la suma de sus edades era 22

Hace nueve años la edad de Ericka era E - 9

Y hace nueve años la edad de Liliana era L - 9

Entonces tenemos:

(E - 9) + (L - 9) = 22

Así, tenemos un sistema de dos ecuaciones:

E = 3*L

(E - 9) + (L - 9) = 22

Queremos conocer la edad actual de Liliana.

Para ello tenemos que despejar E en una de las ecuaciones.

Podemos ver que en la primer ecaución E ya está aislada, entonces nos saltamos ese paso.

Ahora, reemplazamos E en la otra ecuación:

(E - 9) + (L - 9) = 22

(3*L - 9) + (L - 9) = 22

Ahora podemos resolver esto para L

3*L - 9 + L - 9 = 22

4*L - 18 = 22

4*L = 22 + 18

4*L = 40

L = 40/4 = 10

L = 10

Liliana tiene 10 años.
