Juan's time in the race was 5.04 seconds and Tiauna's was 5.40. Explain who had the faster speed and by how much?

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

391.6 is the correct answer

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
