<u>Answer:</u>
The correct answer option is y = -4.
<u>Step-by-step explanation:</u>
We are to find the equation of the mid-line for the following function:

because 




The range is -7 to -1 so the midpoint is 
Therefore, the equation of the mid-line for the given function is y = -4.
Answer:
-10
Step-by-step explanation:
(1/5)x+4=2
5(1/5)x+4=2)
x+20=10
x = -10
Answer: B Exactly one solution
Step-by-step explanation:
5x+8-7x=-4x+1
-2x+8=-4x+1
-2x+4x=-7
2x=-7
x=-7/2
Answer:
Number of sides is 24.
Step-by-step explanation:
You wanted the number, so it's above.
Answer:
-1
Step-by-step explanation:
Note that
, and this means that every 4 terms, the terms cancel to 0. Therefore, by taking modulo 4, we only need to find
since $i$ has a cycle of 4.
