What is 2x + 4x + 4 = 4(x + 4) and step by step and Highlight / circle the error

mario62 [17]

Answer:

x = 6 and the +4x is wrong

Step-by-step explanation:

2x + 4x + 4 = 4(x + 4)

6x + 4 = 4x + 16

+4x +4x <--( <u>This part is wrong</u> )

10x + 4 = 16

-4 -4

10x = 12

10 10

x = 1.2

Correct steps

2x + 4x + 4 = 4(x + 4)

6x + 4 = 4x + 16

-4x -4x

2x + 4 = 16

-4 -4

2x = 12

2 2

x = 6

Which can be the first step in finding the equation of the line that passes through the points 5,-4 and -1,8 in slope-intercept

zheka24 [161]

Step-by-step explanation:

First step:

Calculate a slope.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

We have the points (5, -4) and (-1, 8). Substitute:

$m=\dfrac{8-(-4)}{-1-5}=\dfrac{12}{-6}=-2$

Put the value of the slope and the coordinates of the point (5, -4) to the equation of a line:

$-4=-2(5)+b$

$-4=-10+b$ <em>add 10 to both sides</em>

$6=b\to b=6$

Finally:

$y=-2x+6$
