HELP ME PLEASE- For the equation b=2a+4, a and b are integers.

The following three assumptions can be made about a and b for the equation above.
Ifa>0,thenb>0.
Ifa=0,thenb≠0.
Ifa<0,thenb<□.
What number is missing from the expression b<□ in the third assumption?

Step-by-step explanation:

if a is less than zero then b will from 4 down to negative infinity

so  b < 4

Does this help at all?   ask me some questions if you really want to learn about math ;)

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base
