Solve the inequality.

-2x - 1 ≥ 9

Question 4 options:

x ≤ -5

x ≥ -5

x ≥ 5

x ≤ - 5

Step-by-step explanation:

Given

- 2x - 1 ≥ 9 ( add 1 to both sides )

- 2x ≥ 10

Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

x ≤ - 5

x ≤ -5

Step-by-step explanation:

-2x - 1 ≥ 9

-2x ≥ 10

Divide both sides by -2

(Flip/reverse the inequality when you multiply/divide by a negative value)

x ≤ 10/-2

x ≤ -5

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.
