What number line represents the solution set for the inequality 3x < –9?
2 answers:
<h2>Answer:</h2>
The solution set of the given inequality is:
(-∞,-3)
<h2>Step-by-step explanation:</h2>We are given a inequality in terms of the variable x by:
We divide both side of the inequality by 3 to obtain the new expression as:
This means that the graph of such a inequality is the set of all the real value which are strictly less than -3( since the inequality is strict)
Hence, the solution set in set-Builder form is:
={all x belonging to real numbers| x<-3}
and in interval form the solution is: (-∞,-3)

Check the picture below.
notice, when dividing we have to put the dividend in descending order, now, the cubic, square and single terms are there, but they have a coefficient of 0, as you see in the picture in green, so we add those properly.
