Question

Solve the inequality. Graph the solution.Z/4 is less than or equal to 12.

Answer 1

You have the following inequality:

z/4 ≤ 12

To solve the previous inequality you proceed as follow:

z/4 ≤ 12 multiply both sides by 4

z ≤ 48

Hence, the solution is z ≤ 48

when you want to graph a solution of the form "z lower or equal than", you draw a black point, that means the solution are all number lower than 48, including 48.
