You haven't provided the parallelogram , therefore, I cannot give an exact answer.
However, I will help you with the concept.

<u>When reflecting a point across the line y = x:</u>
We swap the values of x and y while keeping their sign the same.

<u>This means that:</u>
(x,y) ............> reflection across y = x ..........> (y,x)

<u>Examples:</u>
(2,3) ..............> reflection across y = x ............> (3,2)
(1,-4) ..............> reflection across y = x ............> (-4,1)
(-3,6) ..............> reflection across y = x ............> (6,-3)
(-5,-7) ..............> reflection across y = x ............> (-7,-5)

Based on the above, all you have to do is get each point of the parallelogram and swap its x and y coordinates to get its image when reflected across y = x

Hope this helps :)

How to find variables of these #2 &amp; #3

So... hmmm if you check the first picture below, for 2)

we could use the proportions of those small, medium and large similar triangles  like  \bf \cfrac{small}{large}\qquad \cfrac{x}{12}=\cfrac{6}{x}\impliedby \textit{solve for "x"}&#10;\\\\\\&#10;\cfrac{small}{large}\qquad \cfrac{z}{18}=\cfrac{6}{z}\impliedby \textit{solve for "z"}&#10;\\\\\\&#10;\cfrac{large}{medium}\qquad \cfrac{y}{12}=\cfrac{18}{y}\impliedby \textit{solve for "y"}

now.. for 3) will be the second picture below


\bf \cfrac{large}{medium}\qquad \cfrac{x+10}{2\sqrt{30}}=\cfrac{2\sqrt{30}}{10}\impliedby \textit{solve for "x"}&#10;\\\\\\&#10;\textit{now, because you already know what "x" is, we can use it below}&#10;\\\\\\&#10;\cfrac{large}{small}\qquad \cfrac{z}{x}=\cfrac{x+10}{z}\impliedby \textit{solve for "z"}&#10;\\\\\\&#10;\textit{and let us use "x" again below}&#10;\\\\\\&#10;\cfrac{small}{medium}\qquad \cfrac{y}{10}=\cfrac{x}{y}\impliedby \textit{solve for "y"}

The nutrition facts label on a container of dry roasted cashews indicates there are 161 calories in 28 grams. You eat 9 cashews
RoseWind [281]

Answer:

there are 161 calories in 28 gram,then:

one gram of dry roasted cashews contains=161/28=5.75 calories

You eat 12 gram of it, =12*5.75=69 calories


9 cashews  has 12gram, then:

one gram of dry roasted cashews contains= 9/12 = 0.75 cashews

there are total of 28gram in one serving.

Therefore cashews in one serving = 0.75*28=21cashews

a)69 calories

b)21cashews

Simplify x^3y^4/3y^4
yan [13]
The given expression is:
(x^3 * y^4) / (3y^4)

We can notice that the term y^4 is a common term found in both the numerator and the denominator of the given expression, therefore, we can cancel this term from the both numerator and denominator (as if you divided both numerator and denominator by y^4).

Doing this, we will have the simplified form of the expression as follows:
(x^3) / (3)
