See Discussion below
Discussion:
A function f is even if f(-x) = f(x)
f(x) f(-x) Are they equal?
----------------------------------------------------------------------------------------
-x^8 + 2x^6-5x -(-x)^8 + 2(-x)^6 + 5x No
3 abs(x) - 4 3 abs(-x) -4 Yes
log5 x^2 log5 (-x)^2 Yes
(6x)^ (1/7) (-6x)^(1/7) No
e^(x^2-x) e^( (-x)^2+x) No
(x^8 +5x^2)^(-1) ( (-x)^8 + 5 (-x)^2) ^(-1) Yes
Answers with Yes, above are even functions.

P.S. I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!
The answer is 0.7 kilometers
I think it’s answer B. Because % to decimal is 6.14% divided by 100 so the decimal would move to the left two places which in 0.0614
I now completely sure but I think that’s right
Answer: A isn't a function
Step-by-step explanation:
Rules in adding fractions:
1) Make sure that they have common denominator.
5/10 + 3/10
2) Since both fraction have a denominator of 10, add the numerator and place the sum above the denominator
5/10 + 3/10 = (5 + 3)/10 = 8/10
3) Simplify the fraction
8/10 can still be simplified into 4/5
8 ÷ 2 = 4
10 ÷ 2 = 5
5/10 + 3/10 = 4/5
