Which figure represents the image of parallelogram LMNP after a reflection across the line y = x? (see image)
loris [4]

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. This gives you such reflection rule:

(x,y)\rightarrow (y,x).

From the diagram:

L(3,1), M(4,3), N(5,3) and P(4,1).

Using the reflection rule, you can find coordinates of image points:

L'(1,3), M'(3,4), N'(3,5) and P'(1,4).

As you can see, these are coordinates of vertices of the figure C.

Answer: correct choice is option 3 - figure C.

Please Help!<br><br> Find the product of (x + (3+5i))2.
-Dominant- [34]
(x + (3 + 5i))*(x + (3+5i))
= x^2 + x(3+5i) + x(3+5i) + (3 + 5i)^2
= x^2 + 2x(3+5i) + 9 + 6(5i) + 25i^2
= x^2 + 6x +10xi + 9 + 30i - 25
= x^2 + 6x + 10xi + 30i - 16

The following graph shows a proportional relationship.
MAXImum [283]

The constant of proportionality of the given graph is gotten as 4.

<h3>How to find the constant of proportionality?</h3>

The constant of proportionality here is simply the slope of the graph.

Now, we will take two points and use their coordinates to find the slope from the formula;

m = (y2 - y1)/(x2 - x1)

Let us pick 2 points which are;

(1, 4) and (2, 8). Thus;

m = (8 - 4)/(2 - 1)

m = 4/1

m = 4

Thus, the constant of proportionality of the graph is gotten as 4.

What is 83.45 rounded to the nearest tenth?
maksim [4K]
83.45 rounded to the nearest tenth would be 83.5 because the hundredths place is a number of 5 and above (the number in the hundredths place is 5) which means you move the tenths place value up by 1.
