relates to
when
and
has the same cardinality. therefore, R does not have reflective:
For every "", "
" So, X not proper subset of
. So, R does not havereflexive.
R does not have symmetry:
For every "" ,then, "
" is not true because
not relate to
. So, R is not symmetric.

Step-by-step explanation:
Table 1.-
Assembling hours finishing hours
Product (tables) x 8 2
Product ( chairs) y 2 1
Availability 400 120
Constrains:
1.-Availability of assembling hours 400
8*x + 2* y ≤ 400
2.-Availability of Finishing hours
2*x + 1*y ≤ 120
3.-General constraints
x ≥ 0 y ≥ 0 integers
