Answer:
aₙ = -2aₙ₊₁
Step-by-step explanation:
According to the sequence given 16, -8, 4, ...
a1 = 16
a2 = -8
a3 = 4
From the values, we can conclude thst;
a1 = -2(-8)
Since a2 = -8, then;
a1 = -2(a2)
Similarly
a2 = -2(4)
a2 = -2a3
The subsequent sequence are;
a3 = -2a4
The nth term will ne;
aₙ = -2aₙ₊₁
Hence the required recursive function is aₙ = -2aₙ₊₁

2(x - 2) + 3(x + 1) = 9
2x - 4 + 3x + 3 = 9 <em>distributed the 2 and 3 on the left side</em>
5x - 1 = 9 <em>added like terms (2x + 3x) and (-4 + 3)</em>
5x = 10 <em>added 1 to both sides</em>
x = 2 <em>divided 5 from both sides</em>
Answer: x = 2
Answer:
Based on the graph, the bird is initially flying from a certain height and not the ground(A). It flies from a certain height to reach a higher altitude and then flies steadily without changing it's altitude until reaches a certain point(B). The bird is perhaps at rest and not moving before it starts to descent down to the ground. The altitude decreases over time at C.

Answer:
Step 3: Use the same width of the compass to draw an arc from point N that intersects the segment NT at a point X.
Step-by-step explanation:
In step 4, Y is the point of intersection of arcs drawn from points X and N. Therefore we need an arc from point N before that
