Answer:
D:y+9=-4(x-4)
Step-by-step explanation:
The positive 9 comes from the top of the graph and its -4 because its on the lower half of the graph.
Answer:
8
Step-by-step explanation:
We could rearange the equation to for it to be 3 - (-5) = ? In this case we would add to get our missing number. Which would be 3+5=8. That is how we get 8 as our final answer and the answer for the blank.

Answer:
(-∞, -4) ∪ [-2, ∞)
Step-by-step explanation:
The solution to the first inequality is ...
-9x +3 > 39
-9x > 36 . . . . . subtract 3 from both sides
x < -4 . . . . . . . divide both sides by -9; reverse > to < because -9 is negative
__
The solution to the second inequality is ...
-5x +6 ≤ 16
-5x ≤ 10 . . . . . . . subtract 6 from both sides
x ≥ -2 . . . . . . divide both sides by -2; reverse ≤ to ≥ because -2 is negative
__
These solution sets are disjoint. The solution of the OR of these inequalities is the union of the solution sets. The graph is shown below. In interval notation, it is described by ...
(-∞, -4) ∪ [-2, ∞)
The -2 has a square bracket because it is included in the set. The curved bracket at -4 indicates it is not included.
