Answer:

Necesitas vender 106.66 camisetas para obtener un beneficio de 300 euros.

Step-by-step explanation:

Con la información proporcionada, puedes decir que el beneficio obtenido es igual a la cantidad total obtenida al vender las camisetas menos el costo. La cantidad obtenida al vender las camisetas es igual al precio por camiseta por el número de camisetas vendidas y el costo es igual al valor pagado por las camisetas mas los gastos de alquiler y de luz. De acuerdo a esto:

Beneficio=12x-(780+200), donde x es el número de camisetas vendidas

Beneficio=12x-980

Ahora puedes reemplazar el beneficio con 300 y despejar x para encontrar las camisetas que necesitas vender para obtener un beneficio de 300 euros:

300=12x-980

300+980=12x

1280=12x

x=1280/12

x=106.66

De acuerdo a esto, la respuesta es que necesitas vender 106.66 camisetas para obtener un beneficio de 300 euros.

Which of the following is an X-intercept of the function f(X)=X^3-5X^2-8X+48
Anton [14]
You have to searh the x values that make f(x) = 0

Factoring this equation is very difficult.

You can divide by x+3 and you will find that the equation can be factored as

(x+3)(x-4)^2

That means that x = -3 and x = 4 make f(x) = 0

Then the points are (-3,0) and (4,0).

\begin{aligned} &y=2x +1 \\\\ &x-y=-3 \end{aligned} ​ y=2x+1 x−y=−3 ​ Is (2,5)(2,5)left parenthesis, 2, comma, 5, right
trapecia [35]

Answer:

Yes

Step-by-step explanation:

Given the system of equations

\begin{aligned} &y=2x +1 \\\\ &x-y=-3 \end{aligned}

We want to determine if (2,5) is a solution of the system.

We can do this by substitution of the given point into the equations and see if it holds.

Given (x,y)=(2,5), x=2, y=5

<u>In the first equation</u>

y=2x+1

5=2(2)+1

5=5

Therefore, <u>the point (2,5) satisfies the first equation.</u>

<u>In the second equation</u>

x-y=2-5=-3

Since our result (-3) is equal to the Right Hand Side, <u>the point also satisfies the second equation.</u>

<u />

Therefore, (2,5) is a solution of the system.
