Question

Solve the following compound inequalities and graph the solution on a number line:

 

-5≤x-4≤13

 

 

-12≤2-5x≤7

Answer 1

-5≤ x-4 

-1 ≤ x 

 

x-4 ≤ 13

x ≤ 17

Thus the solution is -1≤ x ≤ 17   Draw a solid line from -1 to 17 on the X axis. That is the solution. 

 

  -12≤2-5x  

-14 ≤ -5x

14/5 ≥ x

 

2-5x ≤ 7

-5x ≤ 5

x ≥ -1

Draw a solid line from -1 to 14/5 (2.8) on the X axis. That is the solution
