Slope formula
y2-y1/x2-x1
5-3/2-4
2/-2
-1 = slope

y=-1x+b
5=-1(2)+b
5=-2+b
b=7

Your answer:
y= -1x + 7

The measure of each exterior angle of a regular 30-gon is
dezoksy [38]

Answer:

12°

Step-by-step explanation:

So, for your 30-gon, the interior angles total up to (30-2) * 180 = 5040.   Each interior angle is that total divided by the number of interior angles, or 5040/30 = 168º:

 

<u>The measure of each exterior angle is the total divided by the number of angles, or 360/30 = 12º.</u>

Use the given transformation to evaluate the integral. 9 x − 3y 2x − y dA, R where R is the parallelogram enclosed by the lines
hichkok12 [17]

\displaystyle\iint_R(9x-3y)(2x-y)\,\mathrm dA

\begin{cases}u=x-3y\\v=2x-y\end{cases}\implies\begin{cases}x=\frac{3v-u}5\\y=\frac{v-2u}5\end{cases}\implies\mathrm dA=|\det J|\,\mathrm du\,\mathrm dv

where J is the Jacobian matrix for the transformation,

J=\begin{bmatrix}u_x&u_y\\v_x&v_y\end{bmatrix}=\begin{bmatrix}-\dfrac15&\dfrac35\\\\-\dfrac25&\dfrac15\end{bmatrix}\implies|\det J|=\dfrac15

We have

9x-3y=8x+x-3y=\dfrac85(3v-u)+u=\dfrac{24v-3u}5

so that the integral is

\displaystyle\frac1{25}\int_9^{10}\int_0^{10}(24v-3u)v\,\mathrm du\,\mathrm dv=\boxed{\frac{4051}5}

How do you interpret algebraic expressions in terms of their context
NNADVOKAT [17]
Well, it really depends on the context they are in. For instance,
2x^2 + 3x is different than 2xyt + 3xy + 2xyt or
y = 2x + 5 or 2x^3 + 2x^2 + 4x + 4 They all are interpret differently. For instance, one is a line, another is a square and one is a cube.
