Question

Hands On

Answer 1

Answer:

Consider the below figure attached with this question.

Given:

To find:

The number of line that represents the solution of given inequality.

Solution:

We have,

Subtracting 6 from both sides, we get

If an inequality is multiplied or divide by a negative number, then the sign of inequality must be change.

Divide both sides by -4.

The value of x is less than -3. It means number of the left of -3 are included in the solution set but -3 is not included in the solution set.

So, there is an open circle at x=-3 on the number and an arrow from -3  towards left.

Therefore, the correct option is A.
