9. Besides Mr. and Mrs. Brewster, these people were present for the Thanksgiving dinner: their daughter and two of her college friends; a son, his wife, and their twin boys; another daughter
and her husband; a great aunt and neighbors Mr. and Mrs. Yates. If Mrs. Brewster's cake in
problem No. 8 weighed 4 pounds and 6 ounces and is all eaten and she served each person
present an equal portion of cake, how much less than 1/2 pound of cake did each person
get?

well the 1 and -1 are always after the 0 and the 0 is inthe middle. s thats what i would guess. but i dont know what a slope of 2 is sorry

step-by-step explanation:

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

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
