Simplify. <br><br> 4√6+2√6−√6<br><br> A- 5√18<br> B-5√6<br> C-6√6<br> D- 6√18
Aleksandr [31]

Answer:

B

Step-by-step explanation:

Simplifying radicals is similar to collecting like terms in algebra.

Here, the like terms are the radicals

Given

4\sqrt{6} + 2\sqrt{6} - \sqrt{6}

= \sqrt{6}(4 + 2 - 1 )

= 5\sqrt{6} → B

1)  -6y + 17 = 3y - 10

Subtract 3y from both sides.

-6y - 3y + 17 = -10

Subtract 10 from both sides.

-6y - 3y = -12 - 10

Simplify.

-9y = -27

Divide both sides by -9.

y = 3

2)  3x - 32 = -7x + 28

Add 7x to both sides.

3x + 7x - 32 = 28

Add 32 to both sides.

3x + 7x = 28 + 32

Simplify.

10x = 60

Divide both sides by 10.

x = 6

3)  3.2 - 16 = 4a

Simplify.

-12.8 = 4a

Divide both sides by 4.

a = -3.2

4)  16.8 - v = 6v

Add v to both sides.

16.8 = 6v + v

Simplify.

16.8 = 7v

Divide both sides by 7.

v = 2.4

To check all answers, simply plug in the value of the variable that you found, then simplify.

De acuerdo con la siguiente función f(x)=-3x+8, ¿cuál es el punto de intersección de su grafica con el eje y?
Ket [755]

Answer:

El punto de intersección con el eje “y” será (0 ; 8).

Step-by-step explanation:

En este caso la función es f(x)= -3*x + 8, o lo que es lo mismo, y= -3*x + 8

Para encontrar la intersección en y, se debe sustituir a la variable x por 0 por en la función. Una vez hecha la sustitución, es posible resolver la ecuación para encontrar el valor de y.

En este caso:

y= -3*0 + 8

Resolviendo:

y= 0 + 8

y= 8

Otra forma de resolverlo es, siendo la función f(x)= m*x + b (donde m es la pendiente y b la ordenada al origen), el valor b es el punto donde una recta cruza el eje y. En este caso la ordenada al origen tiene un valor de 8.

Entonces <u><em>el punto de intersección con el eje “y” será (0 ; 8).</em></u>
