Answer:
The answer to your question is below
Step-by-step explanation:
A) 2x > -6
x > -6/2
x > -3
It must be a graph with an open circle starting at -3 and then to the right.
It is the first graph.
B) x - 4 < -7
x < -7 + 4
x < -3
The graph must be an open circle starting at -3 and pointing to the left.
it is the second graph.
C) 6 + x ≤ 3
x ≤ -6 + 3
x ≤ -3
The graph must be a closed circle starting at -3 and pointing to the left.
it is the forth graph.
D) -x - 5 ≤ -2
-x ≤ -2 + 5
- x ≤ 3
x ≥ -3
The graph must be a closed circle starting at -3 and pointing to the right.
It is the third graph.

x=-1
im sorry but im not sure what y is
Answer:
The difference between the sample percentage and the population percentage is likely to be less than 4 percent
Step-by-step explanation:
The margin error is the difference between the values of the sample analyzed and the actual population. In reality, the result of the sample analyzed will be different from the actual result. This can be due to approximation error or human error. However, the difference in the two results should not be more than the allowable limit.
