The answer is -6.
First you need to balance, so add 4 to both sides.
2 = -x - 4
Now you need to divide both sides by -1.
6 = -x
Boom.
-6 = x

Need help with this :(

Answer:

B.    m = \frac{3}{2}, y-int = 3

Step-by-step explanation:

To find the slope of the line, we need to plot two points

(2, 6) (-2, 0)

m = slope

Then use the Slope-Formula to Solve for the slope

m = \frac{y2-y1}{x2-x1}        

m = \frac{0-6}{-2-2}

m = \frac{-6}{-4}

m = \frac{6}{4}

m = \frac{3}{2}

The Slope is \frac{3}{2}

The y-intercept is 3 because the line is going 3 units upwards on y axis!

Equation: y = 3/2x + 3

Slope: 3/2

y-intercept: 3

<u><em>Answer:</em></u>

volume of sphere = 288π ft³

<u><em>Explanation:</em></u>

volume of sphere = \frac{4}{3} \pi r^3

where pi is a constant and r is the radius of the sphere

<u>We are given that: </u>

The diameter of the sphere is 12 ft.

<u>This means that</u> the radius = \frac{12}{2} = 6 ft

<u>Substitute with the radius in the above equation to get the volume as follows:</u>

volume = \frac{4}{3} \pi *(6)^3 = 288\pi ft³

Hope this helps :)
