Answer: good luck

Step-by-step explanation:Step 1) Because the first equation is already solved for

y

we can substitute

3

x

+

8

for

y

in the second equation and solve for

x

:

8

x

+

4

y

=

12

becomes:

8

x

+

4

(

3

x

+

8

)

=

12

8

x

+

(

Step 2) Substitute

−

1

for

x

in the first equation and calculate

y

:

y

=

3

x

+

8

becomes:

y

=

(

3

⋅

−

1

)

+

8

y

=

−

3

+

y

=

The solution is:

x

=

and

y

=

Identify the semiregular tessellation. HELP ASAP. PLEASE I AM DESPERATE!!
nignag [31]

Answer:

  see below

Step-by-step explanation:

A <em>regular tessellation</em> involves repeated use of a single regular polygon to cover the plane.

A <em>semiregular tessellation</em> involves repeated use of <em>two or more</em> regular polygons (in the same order around each polygon vertex) to cover the plane.

The first and third diagrams do not involve regular polygons. The fourth involves only a single regular polygon. Hence the second diagram is the one of interest.
