Answer:

The solution would be (-4, -2)

Step-by-step explanation:

To find this simply add the two equations together.

-9x+7y=22

9x-5y=-26

----------------

2y = -4

y = -2

Now we have the y value, we can solve for the x value.

9x-5y=-26

9x-5(-2)=-26

9x+10=-16

9x=-36

x = -4

Determine whether the origin is included in the shaded region and whether the shaded region is above or below the line for the g

kati45 [8]

Answer:

Option: D is correct.

Step-by-step explanation:

since we are given a inequality as:

$y$

Clearly from the graph of the following inequality we could see that the origin is included in the shaded region and the shaded area is below the line.

Also it could be seen that if we put the origin points i.e. (0,0) in the inequality than 0<2 and the condition is true and hence origin is included in the shaded area.

Hence, option D is true.
