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

Well, let's say the numbers are "a" and "b"
so a * b = ab
ok... now, if we reduce "a" by 25%, that means the new size is just 75% of the old one, how much is 75% of a? well, (75/100) * a, or 0.75a
now let's reduce "b" by 50%, that means the new size is 50% or half, how much is 50% of b? well (50/100)*b, or 0.5b

now, the new size of "ab" is just 0.375ab... well, let's revert the decimal format by simply multiplying by 100
0.375 * 100, is 37.5%
the new size of "ab" is just 37.5% of the original "ab"
it decreased by 100 - 37.5 or 62.5%
X is equal to 4
Because RS + ST=RT
So basically x+3x=5x-4
4x=5x-4
-4x -4x
-1x=-4
x=4
Answer:
1
Step-by-step explanation:
21/21 is whole and the a whole as a whole number is equivalent to 1.
