I'm 100% sure the answer is d. II and IV
because $257.72 - $248.53 = $9.19
and $73.98 - $64.79 - 9.19
i hope this helps :)

We substitute the point to obtain;

This simplifies to

Therefore the slope is 5.

Answer:
BCD = ECD
Step-by-step explanation:
they would equal the same thing because it is still the same shape
(2x+3y)+(7x-3y)
First, group like terms together, so (2x+7x) + (3y-3y). Then simplify within the parentheses. 2x+7x = 9x and 3y-3y = 0, so you have 9x, which cannot be simplified any further. The answer is 9x.
