Answer 1

Hii!

___________________________________________________________

Answer:

'Cause both sides were divided by a negative number! ^^

Explanation:

The sign of the inequality was flipped because you divided both sides of the inequality by -4, which is a negative number.

When we divide, or multiply, both sides of an inequality by a negative number, we flip the inequality sign.

Answer 2

See below

Explanation:

When you multiply or divide both sides of an inquality equation by a NEGATIVE number , it reverses the symbol to see this in action:

- 4n >36 Instead of dividing by -4 let's ADD - 4n to both sides

0 > 36 + 4n now SUBTRACT 36 from both sides

-36 > 4n re-arrange just a little

4n < -36 <======== see how the symbol has reversed ???

n < -9
