A graph shows x-3 to be a factor, selection B.
The factorization would be (7x +3)(x -3).
The factorization would be (7x +3)(x -3).

Hey!
Okay, to solve this problem, we'd first have to multiply both sides by two. The reason we do this is to get
on its own.
<em>Original Equation : </em>
< 
<em>New Equation {Changed by Multiplying 2 on Both Sides} :</em>
< 
( )
And we simplify the equation to get our answer.
<em>Old Equation :</em>
< 
( )
<em>New Equation {Changed by Simplification} :</em>
y < -6
<em>So, the equation < -3 simplified is</em> y < -6.
Hope this helps!

<h3>Answer: Choice D</h3>
======================================================
Explanation:
The inequality sign has an "or equal to", which means the boundary line will be solid. We can rule out choices B and C because they have dashed boundary lines.
A solid boundary line means that points on the boundary are part of the solution set.
Now let's see what happens when we plug in a point like (x,y) = (4,0). This will tell us how to shade the blue region.
This is false because -20 is not larger than -1. It's the other way around.
This tells us the point (4,0) is not in the blue shaded region, and it's not on the boundary line either. We can rule out choice A because of this.
The only thing left is choice D, which is the final answer. I recommend plugging a point from this region into the inequality to confirm we have a true statement.
