Answer and explain:

1st person: 70 % throws

70/100x80 = 56 out of 80 throws

2nd person: 60% throws

60/100x80 = 48 out of 80 throws

3rd person 50% throws

50/100x80 = 40 out of 80 throws

56+48+40/80x3 = 77/120​

One equation that gives the estimated number of free throws (all the 3 people) is 77 out of 120. The best player will make about 56 out of 80 free throws.

Answer:

La expresión lineal es; 7y = 6500 - 100x

Step-by-step explanation:

Necesitamos entender que todos los modelos lineales siguen u obedecen la ecuación de una línea recta.

Matemáticamente, la ecuación de una línea recta se puede representar como;

y = mx + c

donde m representa la pendiente de la línea yc representa la intersección en y de la línea.

Para responder adecuadamente a esta pregunta, podemos ver que tenemos dos puntos de trama diferentes. Podemos visualizar nuestro modelo como una gráfica lineal del número de unidades contra el precio. Donde el número de unidades está en el eje y, y el precio está en el eje x.

Verifique el archivo adjunto para ver un diagrama de cómo debe verse la trama.

Ahora, calculemos la pendiente de nuestra línea que tiene 2 puntos en la línea;

(58,100) y (51,200)

Para calcular la pendiente m, podemos usar la relación matemática de la siguiente manera;

m = (y2-y1) / (x2-x1) = (200-100) / (51-58) = -100/7

Ahora tenemos la pendiente pero no tenemos la intersección en y.

Para obtener la intersección con el eje y, utilizamos cualquiera de los dos puntos de datos.

Usaré el segundo;

La ecuación de la línea en ese punto será;

200 = -100 / 7 (51) + c

 Tenemos;

7c = 1400 + 5100

7c = 6500

c = 6500/7

Ahora completemos nuestro modelo lineal ya que ahora tenemos la pendiente y la intersección en y

y = - (100/7) x + 6500/7

7 años = -100x + 6500

o simplemente 7y = 6500-100x

-3x + 4y = 12; 3x - 5y = 18<br> Solve
viktelen [127]
X = -44
y = -30

Solve for y in equation 1.
Plug in the new value for y into equation 2 to solve for x.
Next, plug your x value into either equation to find y. You can choose either, but I picked the 1st equation.
