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:

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
