\left \{ {{- \atop {2(21.5-2y)+2y=30}} \right.Answer:

Step-by-step explanation:

a)

x= gourmet pretzels

y= boxes of strawberries

system will be:

\left \{ {{2x+4y=43 \atop {2x+2y=30}} \right.

b)

\left \{ {{2x+4y=43 \atop {2x+2y=30}} \right. \left \{ {{x=21.5-2y \atop {2x+2y=30}} \right.\left \{ {{- \atop {2(21.5-2y)+2y=30}} \right.\left \{ {{- \atop {43-4y+2y=30}} \right.\left \{ {{- \atop {-4y+2y=30-43}} \right.\left \{ {{- \atop {-2y=-13}} \right.\left \{ {{- \atop {y=\frac{13}{2} }} \right.\left \{ {x=21.5-2(6.5)}} \atop {y=6.5}} \right.\left \{ {{x=8.5} \atop {y=6.5}} \right.

Evaluate the spherical coordinate integral
expeople1 [14]

Rewrite the equations of the given boundary lines:

<em>y</em> = -<em>x</em> + 1  ==>  <em>x</em> + <em>y</em> = 1

<em>y</em> = -<em>x</em> + 4  ==>  <em>x</em> + <em>y</em> = 4

<em>y</em> = 2<em>x</em> + 2  ==>  -2<em>x</em> + <em>y</em> = 2

<em>y</em> = 2<em>x</em> + 5  ==>  -2<em>x</em> + <em>y</em> = 5

This tells us the parallelogram in the <em>x</em>-<em>y</em> plane corresponds to the rectangle in the <em>u</em>-<em>v</em> plane with 1 ≤ <em>u</em> ≤ 4 and 2 ≤ <em>v</em> ≤ 5.

Compute the Jacobian determinant for this change of coordinates:

J=\begin{bmatrix}\frac{\partial u}{\partial x}&\frac{\partial u}{\partial y}\\\frac{\partial v}{\partial x}&\frac{\partial v}{\partial y}\end{bmatrix}=\begin{bmatrix}1&1\\-2&1\end{bmatrix}\implies|\det J|=3

Rewrite the integrand:

-3x+4y=-3\cdot\dfrac{u-v}3+4\cdot\dfrac{2u+v}3=\dfrac{5u+7v}3

The integral is then

\displaystyle\iint_R(-3x+4y)\,\mathrm dx\,\mathrm dy=3\iint_{R'}\frac{5u+7v}3\,\mathrm du\,\mathrm dv=\int_2^5\int_1^45u+7v\,\mathrm du\,\mathrm dv=\boxed{333}
