How many solutions does this equation have? 9(w-9)-2=-7w+7(w-8)

what level of math? also i don't need to be paid if i can you.

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely

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
