I think the scale factor of one block to the arrangement would be 1/9, since the arrangement contains 9 blocks.

So if the length at the top is 12 cm, the length of the bottom of a trapezoid would be 12(1/9) = 4/3

Since we know that each trapezoid holds 3 equilateral triangles, the length of each side and the top of the trapezoidal would be 4/3 x 1/2 = 2/3 cm

The sum of the angles must equal 360 degrees, and because they are made of equilateral triangles, you know that each angle of the triangle must be 60 degrees. So the bottom two angles of the trapezoid are each 60 degrees, and the top two are 360- 120 = 240 divided by 2 angles = 120 degrees each.

PLEASE HELP !! ILL GIVE BRAINLIEST *EXTRA POINTS*.. <br> IM GIVING 40 POINTS !! DONT SKIP :((.

Answer:

m = 1/3

b = -6

Step-by-step explanation:

How to calculate slide (m):

\frac{y_{1} - y_{2} }{x_{1} - x_{2} } = m

x1 = 0

x2 = -12

y1 = -6

y2 = -10

If we put in the values:

\frac{(-6) - (-10)}{0 - (-12)} = m

Subtracting a negative number is the same as adding it:

\frac{(-6) + 10 }{0 + 12} = m

-6 + 10 = 4 and 0 + 12 = 12 so now we have this:

\frac{4}{12} = m

Lets simplify:

4 and 12 can both be divided by 3:

\frac{1}{3}  = m

3 and 1 are prime numbers and cannot be simplified further.

Now we know that m=1/3

Since:

y = mx + b

y = -6

x = 0

m = 1/3

Then:

-6 = 1/3*0 + b

1/3*0 is 0, so we can just remove that part:

-6 = b

that means b is equal to -6

Hope i was able to help!

Help PLEASE!!!!!!!!!!!!!!!

Answer:

1) The graph does represent a function, because it passes the vertical line test.

Step-by-step explanation:

The vertical line test goes over the graph making sure there aren't 2 points together on the same line vertically. Because this passes the vertical line test, meaning there are no points repeating up and down, it is a function.
