Question

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?

Answer 1

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 ;)
