The smith family purchased a new washer and dryer for $1400. they
determined that the monthly cost to operate both would be $20. to
determine the average monthly cost for owning and operating the washer and
dryer over x months mrs. smith uses the function, c(x) = -
1400+20x
*. how
the average monthly cost is less than $40?

answer:

c) the x-coordinate of the center of the circle increases by 3

answer:

idk

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.
