What is the equation of a line that passes through the points (–3, 4) and (2, 8)?
Mrac [35]

Answer:

\frac{y - 4}{x - ( -  3)}  =  \frac{8 - 4}{2  -  (-  3)}  \\  \frac{y - 4}{x + 3}  =  \frac{4}{5}  \\ 5(y - 4) = 4(x + 3) \\ 5y - 20 = 4x + 12 \\  \boxed{4x - 5y + 32 = 0}

<h2>4x-5y+32=0 is the right answer.</h2>

Choose one of the factors of x^3 + 343.
Debora [2.8K]

First, note that 343=7^3. Then use the formula for the sum of perfect cubes:

a^3+b^3=(a+b)(a^2-ab+b^2).

Therefore,

x^3 + 343=x^3+7^3=(x+7)(x^2-7x+49).

The quadratic trinomial x^2-7x+49 couldn't be factored anymore, so the expression x^3 + 343 has two factors x+7 and x^2-7x+49.

Answer: correct choice is A.

Si un celular Cuesta 4500 y tiene un descuento de 76%cuamto vq a pagar por el teléfono
USPshnik [31]

De acuerdo con las definiciones de precio a pagar, porcentaje de descuento y porcentaje remanente, el precio a pagar por el celular es $ 1080.

<h3>¿Cuánto cuesta un celular con descuento? </h3>

En esta situación una persona recibe un descuento por la compra de su celular, el precio a pagar es el producto de multiplicar el coste <em>sin descuento</em> y el porcentaje remanente en forma fraccionaria. El porcentaje remanente se calcula al restar el descuento del cien por ciento. A continuación, procedemos al cálculo requerido:

x = 4500 × (1 - 76/100)

x = 1080

De acuerdo con las definiciones de precio a pagar, porcentaje de descuento y porcentaje remanente, el precio a pagar por el celular es $ 1080.
