PL HELP IM BEGGING YOU Make your own real-world problem that can be modeled by the fraction: y=100(2)^x

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

alright well the answers to your question is

2xy/9 hope this have a nice day : )

step-by-step explanation:
