Solve the system.<br> y= 22 – 10x + 15<br> y=-10
Yuliya22 [10]

I will try to solve your system of equations.

y=22;−10x+15y=−10

Step: Solvey=22for y:

Step: Substitute22foryin−10x+15y=−10:

−10x+15y=−10

−10x+(15)(22)=−10

−10x+330=−10(Simplify both sides of the equation)

−10x+330+−330=−10+−330(Add -330 to both sides)

−10x=−340

−10x

−10

=

−340

−10

(Divide both sides by -10)

x=34

Answer:

y=22 and x=34Answer:

3. Problema 2: Suponga que un fabricante de radios tiene la función de costo total C (x) = 43x + 1850 dólares y la función de in
allochka39001 [22]

Responder:

$ 11,137

Explicación paso a paso:

Como no se nos dice qué encontrar, también podemos encontrar el beneficio obtenido por la venta de 351 unidades de radio.

Dado

Función de costo C (x) = 43x + 1850

Función de ingresos R (x) = 80x

Obtener la función de ganancias

P (x) = R (x) - C (x)

P (x) = 80x - (43x + 1850)

P (x) = 80x - 43x - 1850

P (x) = 37x - 1850

Si se fabrican 351 radios, la ganancia obtenida se calculará como se muestra a continuación:

P (351) = 37 (351) - 1850

P (351) = 12,987-1850

P (351) = 11,137

<em>Por lo tanto, la ganancia obtenida de las ventas de 351 radios es de $ 11,137</em>
