Question

If the expression below has a positive value, which in the inequality represents all possible values of x in the expression? -3x. A. X< 0. B. X > 0 C. X ≤ 0. D. X ≥ 0

Answer 1

`x < 0`

Explanation:

Given

The expression is:

`-3x > 0`

Required

Determine the inequality

`-3x > 0`

Divide both sides by -3

`(-3x)/(-3) > (0)/(-3)`

The inequality sign changes after the division because we're dividing be a negative number (-3).

So, we have:

`x < 0`

Hence, the inequality is:
`x < 0`
