math .. i need help!?

Question

Could someone sovle these Systems of inequalities problems for me? thanks


1. -2x + 3y < -6
2. 5x + 3y > -6 and 2y + x < 6
3. 2x - 3y >/ 9 and - x - 4y >/ 8

Answer 1

1)
2x + 3y < -6

a line passes through intercept points
(-3,0), (0,-2)
the region opposite origin without including the line.

2)
5x + 3y > -6
2y + x < 6

two lines intersect at the point
(-30/7, 36/7)

shade the region between two lines except lines
Here is the solution region.

the first line intersection points (-6/5,0) , (0,-2)

the second line intersection points
(0,3), (6,0)


3)
what is /9
is it square root?
