1 answer:
La ecuación de la linea es: y = -4x + 2600
<h3>¿Como determinar la relación lineal?</h3>
Tenemos dos puntos para nuestra linea, los cuales son (350, 1200) y (320, 1320).
Con esos dos puntos podemos obtener la pendiente de la linea:
Entonces la linea es algo como:
y = (-4)*x + b
Para obtener el valor de b usamos uno de los dos puntos dados, como el primero:
1200 = (-4)*350 + b
1200 = -1400 + b
1200 + 1400 = b = 2600
Entonces la linea es:
y = -4x + 2600
Si se vendieron 35 unidades, podemos reemplazar:
35 = -4*x + 2600
4x = 2600 - 35 = 2565
x = 2565/4 = 641.25
Es decir, el precio es $641.25

The solution for the given equations x + 3y = 5 and x - 3y = -1 are x=2 and y=1.
Step-by-step explanation:
The given is,
......................................(1)
....................................(2)
Step:1
By elimination method,
Subtracting Equations (1) and (2),
( - )
( ) + (
) = (
)
= 6
= 1
Step:2
Substitute the value of y in equation (1),
+ ( 3 × 1 ) = 5
= 5-3
= 2
Step:3
Check for Solution,
Substitute the values of x and y in Eqn (1),
2 + ( 3 × 1 ) = 5
5 = 5
Result:
The solution for the given equations x + 3y = 5 and x - 3y = -1 are x=2 and y=1, by elimination method.
