Answer:

2. yes; the equation can be written as y = kx; k = 1

Step-by-step explanation:

x-y = 0

That means x and y have to be the same value.

If you multiply a number by 1, you get the same thing.

If you multiply x by one, you get y (the same value).

Hope this helps!

I NEED HELP PLS!!!!
hram777 [196]

Answer:

15

Step-by-step explanation:

For these kind of problems, its best to use a Venn Diagram.

Lets break down the information:

<em>There are 50 students total.</em>

<em>25 take Math competiton classes.</em>

<em>29 take Geometry</em>

<em>12 take history and </em><em><u>no math classes</u></em>

<em>19 take </em><em><u>both math classes</u></em>

Now, make a Venn Diagram.

[Look at the photo attached. Also, the blank spaces in the Venn Diagram are ones that no student takes.]

The 12 taking history and no math classes and 3 kids not taking any of those classes look like they're the only ones not taking either math class.

12 + 3 = 15.

So the answer is 15.

[I'm not sure if this is correct or if I made a mistake so please let me know! Thank you! I hope this helps!]

:)

What is the slope of this graph
Elden [556K]

Answer:

The slope of the line = m = 2

Step-by-step explanation:

Given

The points

  • (0, 0)
  • (1, 2)

To determine:

The slope of this graph

Determining the slope between (0, 0) and (1, 2)

  • (x₁, y₁) = (0, 0)
  • (x₂, y₂) = (1, 2)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [2 - 0] / [1 - 0]

               = 2 / 1  

Thus, the slope of the line = m = 2

Which shape could be thought of as being created by stacking congruent polygons
Colt1911 [192]

When they talk about congruent polygons, they meant geometric figures that are all equal in shape and size.

It's angled, and the side length is equal too.

When you piled equal polygons, you'll end up with what we call prisms. It's the 3D form of a polygon.

If you stack squares, you'll have a cube.

If you stack octagons, you'll have an octagon prism.
