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

Answer:
Y/X = 2/3 x^2 + 16/3
Y= 2/3 x^3 + 16/3 x
Just replace y with y/X and X with x^2
Answer:
The first car was traveling 70 mph, while the second was driving 50 mph.
Step-by-step explanation:
Set the cars as a proportion:

X represents the speed of the second car. By cross multiplying, you get the following equation:

You solve by distributing 150 to get 210x = 150x + 3000.
Solving for x gets you 50.
That means the first car was going at 50 mph. Adding 20, you get 70 as the speed for the second car.
Answer:
Answer = 235.5
Step-by-step explanation:
Cone volume formula is V = 1/3 * pi * r^2 * h
V = 1/3 * 3.14 * 5^2 * 9
V = 235.5
