Answer:

The correct option is D

Step-by-step explanation:

The given expression is:

-8x^3-2x^2-12x-3

Group the first two terms and last two terms together.

(-8x^3-2x^2) (-12x-3)

Take out common from each group

-2x^2(4x+1)-3(4x+1)

(4x+1)(-2x^2-3)

Thus the correct option is D....

How would I graph this inequality?<br> <img src="https://tex.z-dn.net/?f=7x%2B3y%5C%20%20%5Ctextless%20%5C%206-5x" id="TexFormul

Answer:

the graph in the attached figure

Step-by-step explanation:

we have

7x+3y

isolate the variable y

Subtract 7x both sides

3y

3y

Divide by 3 both sides

y

The solution of the inequality is the shaded area below the dashed line

The equation of the shaded line is y=-4x+2

The slope of the dashed line is negative m=-4

The y-intercept of the dashed line is the point (0,2)

The x-intercept of the dashed line is the point (0.5,0)

To graph the inequality plot the intercepts and shade the area below the dashed line

using a graphing tool
