2(4+x)

Distribute the 2 onto the 4 and x

2*4 = 8
2*x = 2x
—————
2x+8
—————
To evaluate, do 2x+8=0 (isolate x)

Subtract 8 on both sides

2x=-8

Divide by 2

X=-4

I hope I helped you out :)

What is the equation of the line in the following graph? 1)y=x+2

Levart [38]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

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

We have two points (2, 0) and (-2, -4). Substitute:

$m=\dfrac{-4-0}{-2-2}=\dfrac{-4}{-4}=1$

Therefore we have the equation of a line

$y=1x+b\to y=x+b$

Put the coordinates of the point (2, 0) to the equation:

$0=2+b$ <em>subtract 2 from both sides</em>

$-2=b\to b=-2$

Answer: $\boxed{y=x-2}\to\boxed{3)}$

Answer:

x = 137

Step-by-step explanation:

Step-by-step explanation:

∠43° and ∠x° are same side exterior angles as they are on the same side as the transversal but outside the parallel lines. The 2 angles are supplementary, hence

x + 43 = 180 ( subtract 43 from both sides )

x = 137
