Answer:

5

Step-by-step explanation:

If the contestant has 9 minutes for 45 hotdogs, then you would have to divide 45 by 9 to get the answer. 45 divided by 9 is 5.

Then, to see if your answer makes sense, you would multiply 9 by 5 to see if you get 45, which you do.

What is the equation of BD, simplified?
FromTheMoon [43]

Third option is the correct answer.

Answer:

y = \bigg[ \frac{2b}{(2a - c)} \bigg]x - \bigg[ \frac{2bc}{(2a - c)} \bigg]

Step-by-step explanation:

y - y_1 = m(x - x_1) \\  \\ y - 0 =   \bigg[ \frac{2b}{(2a - c)} \bigg]  (x - c) \\  \\ y = \bigg[ \frac{2b}{(2a - c)} \bigg]x - \bigg[ \frac{2b}{(2a - c)} \bigg]c \\  \\  \purple { \boxed{ \bold{y = \bigg[ \frac{2b}{(2a - c)} \bigg]x - \bigg[ \frac{2bc}{(2a - c)} \bigg]}}} \\

~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill&\$600\\ P=\textit{original amount deposited}\\ r=rate\to 8\%\to \frac{8}{100}\dotfill &0.08\\ t=years\dotfill &1 \end{cases} \\\\\\ 600=P(0.08)1\implies \cfrac{600}{0.08}=P\implies 7500=P

(7p^(2)+3p)-(5p^(2)+4)<br> solve for standard form and show how you got it
inna [77]

\huge \boxed{\mathfrak{Question} \downarrow}

  • ( 7 p ^ { 2 } + 3 p ) - ( 5 p ^ { 2 } + 4 ). Solve for standard form.

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

( 7 p ^ { 2 } + 3 p ) - ( 5 p ^ { 2 } + 4 )

To find the opposite of 5p²+4, find the opposite of each term inside the bracket.

7p^{2}+3p-5p^{2}-4

Combine 7p² and -5p² to get 2p².

\boxed{ \boxed{ \bf \: 2p^{2}+3p-4 }}
