Answer:

$5 = (3x - 13) \\ 5 = 3x - 13 \\ 5 + 13 = 3x \\ 18 = 3x \\ \frac{18}{3} = x \\ x = 6 \\$

$6 = (x + 13) \\ 6 = x + 13 \\ 6 - 13 = x \\ x = ( - 7) \\$

Boyle's Law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is 7L, the pressu

$\bf \qquad \qquad \textit{inverse proportional variation}\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\

$\bf \textit{"volume of a gas varies inversely with the pressure"}\quad v=\cfrac{k}{p}

\textit{we also know that }
\begin{cases}
v=7\\
p=410
\end{cases}\implies 7=\cfrac{k}{210}\implies 1470=k
\\\\\\
thus\qquad \qquad \boxed{v=\cfrac{1470}{p}}
\\\\\\
\textit{when p=287, what is \underline{v}?}\qquad v=\cfrac{410}{287}$

What is the radius of the circle given by the equation below?

Dmitry [639]

Answer:

Step-by-step explanation:

First, you gotta complete the square!

x^2+12x+36 = (x+6)^2

y^2-12y+36 = (y-6)^2

So, we have (x+12)^2 + (y-6)^2 = -56 + 36 + 36

The right side of the equation is the radius^2.

Simplify:

-56 + 36 + 36 = 16

The square root of 16 is 4, so the answer is C!
