7. the value of y varies directly with x, and y = -3 when x = 1. find y when x = -6.
8. the value of y varies directly with x, and y = 6 when x = 18. find y when x = 12.
9. cameron earns $5 per hour at her after-school job. the total amount of
her paycheck varies directly with the amount of time she works. write a direct
variation equation for the amount of money y that she earns for working x hours.
then graph.

step-by-step explanation:

32

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
