Ifj(x) = -x - 4 and j(x) = 2, solve for x.

1 answer:

5 0

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

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

Answer:

volume of sphere = 288π ft³

Explanation:

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

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

We are given that:

The diameter of the sphere is 12 ft.

This means that the radius = $\frac{12}{2} = 6 ft$

Substitute with the radius in the above equation to get the volume as follows:

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

Hope this helps :)
