A new cell phone company is trying to decide on a price for their new cell phone. They hired a marketing company which gave them the equation
P(x) = −0.6(x − 100)(x − 400) where x is the price of the phone, and P(x) is the profit they can
make.

step-by-step explanation:

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
