Juana compró una camioneta 4x4 a S/ 42 000; además, sabe que la camioneta se depreciará (bajará su precio) en forma lineal duran
prohojiy [21]

Answer:

Una relación lineal es de la forma:

y = a*x + b.

donde a es la pendiente y b es la ordenada al origen.

en este caso, y es el precio de la camioneta, x es el numero de años que pasaron, a es la razon de depreciación de la camioneta y b es el precio inicial de la camioneta, b = $42,000.

Sabemos que después de 5 años, el precio de la camioneta es 21,000, entonces podemos resolver:

$21,000 = a*5 + $42,000

a*5 = $21,000 - $42,000 = -$21,000

a = -$21,000/5 = -$4,200

Esto significa que el precio decae $4,200 por año

vitfil [10]
S=small pizzas
p=pasta dinners

s+p=1600

9s+13p=15600
multiply first equaiton by -9 and add to the second one

-9s-9p=-14400
<u>9s+13p=15600 +</u>
0s+4p=1200

4p=1200
divide by 4
p=300

sub back

s+p=1600
s+300=1600
minus 300 both sides
s=1300
