Martha made 3 birthday cards and she wants to make more. if she makes 5 cards an hour, How many cards will she have after 6 hour
frozen [14]
Well, since she makes 5 cards in ONE hour, we'll just multiply 5 times 6 to find out the total amount of cards made in 6 hours, which is 30. HOWEVER, we mustn't forget to add the amount of cards BEFORE she began making 5 cards per hour, which is 3, so 30 + 3 = 33. She made 33 cards after 6 hours. c:

How do i solve this question?
Andrews [41]

when it comes to checking if a function is even or odd, it boils down to changing the argument, namely x = -x, and if the <u>resulting function is the same as the original</u>, then is even, if the <u>resulting function is the same as the original but negative</u>, is odd, if neither, well then neither :).


anyway, that said, let's first expand it and then plug in -x,


\bf f(x)=(x^2-8)^2\implies f(x)=(x^2-8)(x^2-8)\implies f(x)=\stackrel{FOIL}{x^4-16x^2+64}\\\\[-0.35em]~\dotfill\\\\f(-x)=(-x)^4-16(-x)^2+64\qquad \begin{cases}(-x)(-x)(-x)(-x)=x^4\\(-x)(-x)=x^2\end{cases}\\\\\\f(-x)=x^4-16x^2+64\impliedby \stackrel{\textit{same as the original}}{Even}
