The inverse relation would be each of these ordered pairs switched.
{(1, -4), (3, -4), (-8, 0), (-9, 8)}
This is because when you create an inverse equation, all of the inputs become outputs and all of the outputs become inputs. Therefore, the ordered pairs simply switch.
" · " - product
" - " - difference
13 · (8 - (-10)) = 13 · (8 + 10) = 13 · 18 = 234
Answer:
the answer is 123 123+156=279.
