Step-by-step explanation:

A) x is less than 0

if x is less than 0, x could be -10

which is not positive

b) x>0 is x is greater than 0, x could be 5 which is positive

c) x is less than or equal to 0, this inequality could mean that x is -10 which is not positive

Answer:

The expression A represents all possible value of x in the expression

Step-by-step explanation:

Taking positive values as those above zero (not including zero) Then:

If expression - 3x is positive we may right this as :

-3x>0

Now, we may simplify x. The import thing is that, when we multiply aN  inequality by a negative number, we change the side of the inequality. To simplify x in the later expression we multiply by (-1/3)

-3x * (-1/3) > 0 * (-1/3)

x <0

Multiplication by a negative constant changes the order of the inequality giving as a result option A : x <0
