Equation 2x²-5x+1 has roots alpha and beta. Form quadratic equation with roots (alpha² + 1/alpha²) and (beta²+1/beta²)​

Answer:

see explanation

Step-by-step explanation:

Since AL bisects ∠ KAT then ∠ 1 = ∠ 2

(30)

7x + 3 = 6x + 7 ( subtract 6x from both sides )

x + 3 = 7 ( subtract 3 from both sides )

x = 4

(32)

SAT is a straight line , then

∠ 1 + ∠ 2 + ∠ 3 = 180° , then

x + x + 4x = 180

6x = 180 ( divide both sides by 6 )

x = 30

(34)

Similar to (32)

x + 12 + x + 12 + 6x - 20 = 180 , that is

8x + 4 = 180 ( subtract 4 from both sides )

8x = 176 ( divide both sides by 8 )

x = 22

Answer:

30) x= 4

32) x=30

33) x=22

Answer:

length between is 8.54 units

Step-by-step explanation:

Formular:

[tex] { \bf{ = \sqrt{ {(x_{1} - x_{2}) }^{2} + {(y_{1} - y_{2}) }^{2} } }}[/tex]

x1 is -4

x2 is 4

y1 is 4

y2 is 1

[tex] = \sqrt{ {( - 4 - 4)}^{2} + {(4 - 1)}^{2} } \\ = \sqrt{64 + 9} \\ = \sqrt{73} \\ = 8.54 \: units[/tex]

Answer:

Distance = 8.25 units

Step-by-step explanation:

use the formula :

√ (x2 _ x1) + (y2 - y1)

where ,

x2 = 4

x1 = -4

y2 = 1

y1 = -1

The answer is A because x-1 means moving left 1 on the x axis. As well, y+4 means moving 4 up on the y axis.

Queremos encontrar una expresión algebraica que representa la situación dada.

Encontraremos que está es: 4*D + 3

Lo primero que debemos hacer es definir la variable.

Definamos D como la distancia que Margarita recorre en la primer semana.

En la segunda semana, Margarita recorre un kilometro más que en la primera, entonces en la segunda semana Margarita recorre:

D + 1km

En la tercera semana, Margarita recorre el dolbe de km recorridos en la segunda.

En la segunda ella recorrio D + 1km, y el doble de eso es:

2*(D + 1km) = 2*D + 2km

La distancia total recorrida sera la suma de las 3 semanas:

D + (D + 1km) + (2*D + 2km)

Simplificando los km, así solo queda una expresión algebraica, obtenemos:

D + (D + 1) + (2*D + 2)

Podemos simpliicar esto para obtener:

D + D + 1 + 2*D + 2

(D + D + 2*D) + (1 + 2)

4*D + 3

Entonces la representación algebraica simpliicada de los kilómetros recorridos durante el entrenamiento es:

4*D + 3

Answer:

- 11

Step-by-step explanation:

let the number be n , then

n + 5 = - 6 ( subtract 5 from both sides )

n = - 11

The number is - 11

Answer: -11

Step-by-step explanation:

Let x be the number

Set equation

x + 5 = -6

Subtract 5 on both sides

x + 5 = -6 - 5
