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:

for 11,000 she had no tax

32,000 of which she had to pay at a rate of 20%

10% of 32,000 = 3200 which you then multiply by 2

6400 - save this for later

she has 2,600 of which she has to pay 40% tax

260 x 4 = 1040

add 1040 + 6400 together and you get 7440 which is how much she payed
