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:
480,000
Step-by-step explanation:
Either plug it in to a calculator or write it out. It is easiest to just plug it in to the calculator though.

The slope is 5/3
For the graph, we have to see that (3,5) and (21,35) are in the line, , or that the equation of the line is

In the case A), a point in the line is (3,5) so the answer is A.
Then it would be 9/10 don't you know anything times 1 is its self even fractions
Answer:
Step-by-step explanation:
If the smallest number is 'x', then the other number = x +1
x*(x+1)= 420
Use distributive property
x*x + x*1 = 420
x² + x - 420 =0 ------> this is the required quadratic equation.
