Answer:

Step-by-step explanation:

1. We have the inequalities 2x > -6 and x-4<3

So, we get,

2x > -6 ⇒ x > -3 and x-4<3 ⇒ x < 7.

Thus, the solution is given by x > -3 and x < 7 i.e. -3 < x < 7 given by figure 1.

2. We have the inequalities x + 5 > 2x + 1 and -4x < -8

So, it gives us,

x + 5 > 2x + 1 ⇒ 4 > x i.e. x < 4 and -4x < -8 ⇒ x > 2.

Then, the solution is given by x < 4 and x > 2 i.e. 2 < x < 4 given by figure 2.

3. We have the inequalities -3x < -6 or x+5 < -2

The solution is,

-3x < -6 ⇒ x > 2 or x+5 < -2 ⇒ x < -7.

Thus, the solution is given by x > 2 or x < -7 given by figure 3.

4. We have the inequalities x-2 > 2x+1 or -2x-2 < -10

We get,

x-2 > 2x+1 ⇒ x < -3 or -2x-2 < -10 ⇒ -2x < -8 ⇒ x > 4

So, the solution is given by x < -3 or x > 4 given by figure 4.
