Answer:
D 3x+6 ≤ 3
Step-by-step explanation:
There is a closed circle at -1
That means there is an equals to
The line goes to the left so it is less than
x ≤ -1
We can eliminate B and C since they do not have an equals to
A 2x+5 ≤ 1
Subtract 5 from each side
2x ≤ 1-5
2x≤ -4
Divide by 2
x ≤ -2
Not this one
D 3x+6≤ 3
Subtract 6 from each side
3x≤ 3-6
3x≤ -3
Divide by 3
x ≤ -1
