Which equation can be used to represent this information?

r=s+5

Step-by-step explanation:

So, letsgo over what we know:

The regular price is r

The sale price is s

Now lets compare the difference between r and s:

10r = 5s

20r = 15s

30r = 25s

What is the difference between the r and s value in each situration?

Well, from what I can see, r is always 5 more than s.

This can be writen as:

r = s+5\

So this is our equation, for if you plug in any number for s, you will get an accurate r value.

For instance, if you say s is 25:

r=25+5

=

r=30

This looks just like the 30r=25s in the table above.

So:

r=s+5

Hope this helps! :)

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
