Okay. First thngs first, let's divide each of them. 2.6/1.3 is 2. Now in terms of exponents, we would just simply subtract the powers, because we are doing division. 9 - 2 is 7. The value of the expression is 2 * 10^7. Even writing the problem out in number form (2,600,000,000/130), you can still see the answer to the problem as 20 million. The answer is B.
Answer: 1/2= 5/10
5/10 - 3/10 = 2/10 or 1/5
so planet X is 1/5 of a light-year closer
Step-by-step explanation:
Part 1- 12 leaves for every three bugs
Part 2- 4 leaves for every one bug
Part 3- ratio is 1:4
Since the domain are the x-values of the function, we need to find the y-values using those x-values.
- for x=

,

. Now we have our first ordered pair:

- for

,

which gives us our next ordered pair:

- for x=2,

, so (2,1)
- for x=4,

, so (4,2)
- for x=8,

, so our last order pair is (8,3)
Finally we can plug the points and joint them to create our graph:
