AAS
Step-by-step explanation:
Paralell is smae slope so it is
2x+3y=c
find c
given
(9,-3)
x=9
y=-3
evaluate to find the constant, c
2(9)+3(-3)=c
18-9=c
9=c
the equation is 2x+3y=9
8.3 is the decimal for the first model and for the second model it is 4.8. Now you just need to add them and you should get 13.1 as your answer. If helped mark me the brainiest!!
