To know while working with inequality equations:

- When multiplying or dividing by a negative, you want to flip the direction of the inequality sign. < becomes >, etc

- When graphing, if it is only less/greater than (< or >) the dot will be open

- When graphing, if it is less/greater than and equal too (≤ or ≥) the dot will be closed

- Then, if the x value is on the left side, the arrow will go in the direction of the inequality sign

[3] Divide both sides by -4, flip the sign

-4x ≥ -36

x ≤ 9

[4] Divide both sides by -0.4, flip the sign, and then I flipped the equation to make it easy to graph

3 > -0.4x

-7.5 < x

x > -7.5

[5] Divide both sides by -2.2, flip the sign

-2.2x ≤ -6.6

x ≥ 3

[6] Multiply both sides by -8, flip the sign


(x)/(-8) > 2

x < -16

See attached for the graphs.
