nghe
B. Multiply the top equation by 3 and the bottom equation by 4
O c. Multiply the top equation by
-3 and the bottom equation by 2
OD. Multiply the top equation by 1/3
h

i think 1: 2

step-by-step explanation:

17

step-by-step explanation:

51/3=17

thus 17 is your answer.

i think the answer is 90 hope this

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
