Answer 1

\[\frac{ 3 }{ 4 }x \ge 9\]
What we need to do is look for the value of x to make all that 9.
So let's transform it to an equation:
\[\frac{ 3 }{ 4 }x=9\]
So, let's solve that for x.
\[x=\frac{ 9 }{ \frac{ 3 }{ 4 } }\]
knowing how to do fraction division we get:
\[x=\frac{ 36 }{ 3 }\]
so we get x=12.

Good! now, what we need to do is position it in the number line to see what values we can take and what values we can't:

Answer 2

With the drawing, we say that when x takes values higher than 12, the equation is greater than 9
and when x is less than 12, the equation is less than 9.
and they ask us foe what values x is equal and greater than 9.
