Paul inherited a stamp collection. Since receiving the collection, Paul has gone to the store and bought the same number of new stamps each week to add to his collection. The equation shown below can be used to
determine the number of stamps (y) in Paul's stamp collection x weeks after he inherited the stamps.
y = 3x + 40
Based on the equation, which statement is true?
A. The stamp collection had 3 stamps in it when Paul inherited it.
B. So far, Paul has purchased 40 additional stamps for the collection.
C. Since inheriting the collection, Paul has bought 3 new stamps each week.
D. Six weeks after he inherited the collection, Paul's stamp collection contains 18 stamps.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

step-by-step explanation:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
