Answer:

23 x + 62

Step-by-step explanation:

Simplify the following:

5 (4 x + 12) + 3 x + 2

5 (4 x + 12) = 20 x + 60:

20 x + 60 + 3 x + 2

Grouping like terms, 60 + 20 x + 3 x + 2 = (20 x + 3 x) + (60 + 2):

(20 x + 3 x) + (60 + 2)

20 x + 3 x = 23 x:

23 x + (60 + 2)

60 + 2 = 62:

Answer: 23 x + 62

Answer:

The value of x is 2.

Step-by-step explanation:

First, you have to make the left side into 1 fraction by making the denorminator the same :

$\frac{x}{x - 2} + \frac{1}{5}$

$= \frac{5x}{5(x - 2)} + \frac{x - 2}{5(x - 2)}$

$= \frac{5x + x - 2}{5(x - 2)}$

$= \frac{6x - 2}{5(x - 2)}$

Then you have to do cross multiplication :

$\frac{6x - 2}{5(x - 2)} = \frac{2}{x - 2}$

$(6x - 2)(x - 2) = 5(2)(x - 2)$

$6 {x}^{2} - 12x - 2x + 4 = 10x - 20$

$6 {x}^{2} - 14x + 4 = 10x - 20$

$6 {x}^{2} - 14x + 4 - 10x + 20 = 0$

$6 {x}^{2} - 24x + 24 = 0$

$6( {x}^{2} - 4x + 4) = 0$

${x}^{2} - 4x + 4 = 0$

${x}^{2} - 2x - 2x + 4 = 0$

$x(x - 2) - 2(x - 2) = 0$

$(x - 2)(x - 2) = 0$

$x = 2$

Given the equation below, find the x and y−intercepts by completing the table.What is the problem with using these intercepts to

kvasek [131]

$-4x+2y=0$

In order to find the x-intercept we need to make y=0

$-4x+2(0)=0$

Then we isolate the x

$-4x=0$ $x=0$

x y Ordered Pair type of intercept

0 0 (0,0) x-intercept

Now for the y-intercept we need to make x=0

$-4(0)+2y=0$

we isolate the y

$2y=0$

$y=0$

0 0 (0,0) y-intercept

ANSWER

0 0 (0,0) x-intercept
