(8c-9b)(x-5a)+(3x+3c)(6a-2b)

Veremos que el precio de venta es el 158% del costo.

Sabemos que con el descuento del 15%, el vendedor gana 35% del costo.

Es decir, si el costo es C, entonces el precio al que se vende la computadora es:

P' = (1 + 0.35)*C = 1.35*C

Pero, esto es con un 15% de descuento. Entonces si el precio de venta es P, tendremos:

P' = (1 - 0.15)*P = (0.85)*P

Reemplazando esto arriba tenemos:

(0.85)*P =  1.35*C

Resolviendo para P:

P = 1.35*C/0.85 = 1.58*C

Para obtener el porcentaje, multiplicamos el coeficiente por 100%.

1.58*100% = 158%.

Es decir, el precio de venta es el 158% del costo.

The exponential equation that represents how many grams of the compound will remain after 8 hours is:

B: C=260(0.962)^8

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

A radioactive compound with mass of 260 grams decays at a rate of 3.8% per hour, hence the equation for the mass after t hours is given by:

[tex]A(t) = 260(1 - 0.038)^t[/tex]

[tex]A(t) = 260(0.962)^t[/tex]

After 8 hours, the amount is given by:

[tex]A(t) = 260(0.962)^8[/tex]

Hence option B is correct.

Answer:

5 + i

Step-by-step explanation:

the Fundamental theorem of Algebra states that a polynomial of gegree n has n zeros , some of which may be complex.

A polynomial of degree 3 will therefore have 3 zeros

given x = 1 and 5 - i are two of the zeros

Complex zeros occur as conjugate pairs , then

5 - i is a zero then 5 + 1 is also a zero

the 3 zeros are x = 1 , x = 5 - i and x = 5 + i

Answer: C (0,5)

Step-by-step explanation:

So firstly you're going to try to solve the inequality, so what I did first is used the second equation because if I divide both sides by 3, I'm able to get the y by itself:

6x+3y>/=15, 6/3=2, 3/3=1, 15/3= 5

So now its: 2x+y>/=5

now I should get the y by itself by subtracting 2x from both sides to get

y>/=15-2x, now if we wanted to plug it in to the top equation, we could make it as, y=15-2x because the it is GREATER THAN OR EQUAL TO.

so to plug it in to the first equation we get:

6x-2(15-2x)<10,

x<4, to find y we just plug it in to any equation now we have x, so I did

6(3)-2y<10

18-2y<10

-18        -18

-2y<10

divide both sides by -2 (flips the equation sign)

y>4,

So take consider both X and Y values, C would be correct because X is less than four and 0 is less than four, and 5 is greater than four.

Let the number of hamburgers = x

x + x - 56 = 394                           Combine the left

2x - 56 = 394                               Add 56 to both sides

2x - 56 + 56 = 394 + 56              Combine

2x = 450                                       Divide both sides by 2

2x/2 = 450/2
