Answer:
-64
Step-by-step explanation:
If
y=x^2
and the x represents -8
Your answer will be -64
By saying that x=(-8) all you have to do is plug in the negative 8 to the original equation of y=x^2. This would make it y=(-8)^2
When you plug in negative 8 to the second power into the calculator your answer will be -64

The sum of the 8 terms of the series 1-1-3-5- ... -13 is -48
The given sequence is:
1,-1,-3, . . -13
and there are 8 terms.
The related series of this sequence is:
1-1-3-5- ... -13
Notice that the series is an arithmetic series with:
first term, a(1) = 1
common difference, d = -1 - (1) = -2
last term, a(8) = -13
To find the sum of the series, use the sum formula:
S(n) = n/2 [(a(1) + a(n)]
Substitute n = 8, a(1) = 1, a(n) = a(8) = -13 into the formula:
S(8) = 8/2 [1 + (-13)]
S(9) = 4 . (-12) = -48
