Answer:
see explanation
Step-by-step explanation:
Given
2z + 4 ≤ - 2 ( subtract 4 from both sides )
2z ≤ - 6 ( divide both sides by 2 )
z ≤ - 3
solution is x ∈ ( - ∞, - 3 ]
The parenthesis on the left means that x cannot equal - ∞
The ] on the right means that x can equal - 3

Answer:
(-∞ , -3]
Step-by-step explanation:
NOTE:__________________________________________________
in order to solve inequality like this we need to isolate the variable z and that’s what we will do in the next few steps___________________
>step 1: subtract 4 from both sides
[tex]2z+4\leq -2\\\\means\\\\2z\leq -2-4\\\\then\\\\2z\leq-6[/tex]
>step 2: divide both sides by 2
[tex]2z\leq-6\\\\then\\\\z\leq-3[/tex]
>Interval notation :
(-∞ , -3]
