Which ordered pair satisfies the inequality y < 2x + 6? Check all that apply.
A. (-1,8)
B. (-3, -12)
C. (0, 12)
D. (-2, 10)
E. (0,0)

Option B:

Option E:

Explanation:

The inequality is

Now, we shall determine the ordered pairs which satisfy the inequality.

Option A:

Substituting, the coordinate in the inequality , we get,

This is not possible.

Hence, the ordered pair does not satisfy the inequality.

Option A is not the correct answer.

Option B:

Substituting, the coordinate in the inequality , we get,

This is possible.

Hence, the ordered pair  satisfy the inequality.

Option B is the correct answer.

Option C:

Substituting, the coordinate in the inequality , we get,

This is not possible.

Hence, the ordered pair does not satisfy the inequality.

Option C is not the correct answer.

Option D:

Substituting, the coordinate in the inequality , we get,

This is not possible.

Hence, the ordered pair does not satisfy the inequality.

Option D is not the correct answer.

Option E:

Substituting, the coordinate in the inequality , we get,

This is possible.

Hence, the ordered pair  satisfy the inequality.

Option E is the correct answer.

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
