Answer:
= - 4 ×
Step-by-step explanation:
Note there is a common ratio between consecutive terms in the sequence.
r = - 8 ÷ - 4 = - 16 ÷ - 8 = - 32 ÷ - 16 = 2
This indicates that the sequence is geometric with n th term
= a
where a is the first term and r the common ratio
Here a = - 4 and r = 2, thus
= - 4
← explicit rule
Answer: C) Closed circle at -5; shading to the left
The given inequality solves to
when we divide both sides by 3. The inequality sign does not change because we didn't divide both sides by a negative number.
The graph has a closed circle at -5 to include this value as part of the solution set. Shading is to the left to indicate values smaller than -5. Overall, the graph says "x can be -5 or smaller". If you wanted to exclude -5, you would say and use an open circle; but that's not the case here.
