Answer:


\boxed {x < 1}

Explanation:

Solve the following inequality:


-9 < -3(5x - 2)

-When you are dividing an integer by a negative integer, then the inequality sign changes. So, divide both sides by
-3:


(-9)/(-3) < (-3)/(-3) + 5x - 2


3 > 5x - 2

-Switch sides:


5x - 2 < 3

-Add
2 to both sides:


5x - 2 + 2 = 3 + 2


5x < 5

-Divide both sides by
5:


(5x)/(5) < (5)/(5)


\boxed {x < 1}

✩ Step-by-step explanation:

✺ Divide both sides by −3. Since −3 is negative, the inequality direction is changed:

  • -3 ÷ -3 = Cancels Out
  • Turns into:
    (-9)/(-3) >5x-2

✺ Divide −9 by −3 to get 3. Since they are both negatives it turns into a positive:

  • -9 ÷ -3 = 3
  • Turns into:
    3 > 5x - 2

✺ Swap sides so that all variable terms are on the left hand side. This changes the sign direction once more:

  • Turns into:
    5x-2<3

✺ Add 2 to both sides:

  • Turns into:
    5x<3+2

✺ Add 3 and 2 to get 5:

  • 3 + 2 = 5
  • Turns into:
    5x<5

✺ Divide both sides by 5. Since 5 is positive, the inequality direction remains the same:

  • 5 ÷ 5 = Cancels Out
  • Turns into:
    x<(5)/(5)

✺ Divide 5 by 5 to get 1:

  • 5 ÷ 5 = 1

✺ So your answer is B,
\boxed{x<1}.
