Answer 2

1. -y > 5 To solve this inequality, we need to reverse the inequality sign when multiplying or dividing both sides by a negative number. In this case, we'll multiply both sides by -1 to isolate y:

-y > 5 (-1)(-y) < (-1)(5) y < -5

So the solution to the inequality is y < -5.

2. -y < -3 Similarly, we'll multiply both sides by -1 to isolate y:

(-1)(-y) > (-1)(-3) y > 3

The solution to the inequality is y > 3.

3. -y < 6.1 Multiplying both sides by -1:

(-1)(-y) > (-1)(6.1) y > -6.1

The solution to the inequality is y > -6.1.

4. -y > 6.1 Multiplying both sides by -1:

(-1)(-y) < (-1)(6.1) y < -6.1

The solution to the inequality is y < -6.1.

5. 1 - 2y > 16 Subtracting 1 from both sides:

1 - 1 - 2y > 16 - 1 -2y > 15

Dividing both sides by -2, remembering to flip the inequality sign:

(-2y) / (-2) < (15) / (-2) y < -7.5

The solution to the inequality is y < -7.5.

6. 29 > y - 27 Adding 27 to both sides:

29 + 27 > y - 27 + 27 56 > y

The solution to the inequality is y < 56.
