70% of a number is what fraction of that number?

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

the correct answer would be c

-5, your answer was correct

well if you have a decimal you have to line them up and make sure the you have everything   straight and then add or subtract some thing with   division and   multiplying so just like them up
