Question

Yes the way these will be numbered is intentional. I am going to have to post quite a few of these today, sorry

 

4. x/-10 > 6

5. 5z >= -75

6. 2y - 2 <14

7. 25 > 1 -3d

8. solve the inequality for 8 and 9. explain all steps

8. 3a - 4 <= 6

9. n/-3 + > 4

 

Answer 1

You need to remember one thing with inequalities. When you multiply or divide by a negative number you need to flip the inequality sign. Otherwise you solve it just as if it were a normal equation.

 

So number 4 for instance:

 

x/-10 > 6

 

* -10      * -10

 

Isolate the x by multiplying both sides by -10:

 

 

x > -60

 

Then flip the inequality sign because you multiplied by a negative number:

 

 

x<-60

 

So x is less than -60

 

 

See, just like a regular equation. I'm sure you can knock out the rest.
