Identify the independent variable and dependent variables, and the rule in function notation. a ticket costs 60$ a. independent: number of tickets ; dependent; cost ; rule: f(t)=60tb. independent; cost; dependent; number of tickets ; rule: f (60t)=tc. independent; number of tickets ; dependent; cost; rule: f(60t)=t d. independent; cost; dependent; number of tickets ; rule: f(t)=t +60

Independent variable is the cost because you cannot change it . dependent variable is the number of tickets because that will vary . . So b is your choice

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
