Which graph shows the solution set of x-9/7x+2<=0

S_A_V [24]

For this case we have the following inequality:
$\frac{x-9}{7x+2} \leq 0$
Solving for the numerator we have:
$x-9 \leq 0$
$x \leq 9$
Solving for the denominator we have:
$7x+2\ \textgreater \ 0$
$7x\ \textgreater \ -2$
$x \ \textgreater \ \frac{-2}{7}$
Therefore, the solution is given by:
$\frac{-2}{7} \ \textless \ x \leq 9$
The graph that shows this solution is the graphic number 3.

option 3

Answer:

m<6 = 130°

Step-by-step explanation:

If m∠2 = 130°, what is m∠6?

Find the diagram attached

From the digram we can see that the vertical lines are parallel. Hence based on geometry;

m<2 = m<6 (corresponding angles)
