Answer:
Step-by-step explanation:
Ok so to find constant of proportionality, you need to find K.
X would be gallons and y is cost.
To find k you need to do k=y/x
k=17.50/5
k=3.5
That's the first one. Now you need to make sure its <em>constant</em> with each one so keep going.
k=35/10
k=3.5
k=52.50/15
k=3.5
For all of those 3.5 was constant.
Because they are constant, that means the data in the graph is a proportion.
An example of an unproportional relationship would be if instead of 15 in the last column, it was 16.
k=52.50/16
k=3.28
That be different from the other 3.5's meaning its not proportional. But that's just an example.
If you need extra help reach out to me and I'll help you best I can. I hope this helps though. <3

Answer:
D. 
Step-by-step explanation:
As the two non-right angles on this triangle measure the same, their corresponding sides must be the same as well. This means that the other side length is 8.
Now that we have two of the side lengths, we can use the Pythagorean theorem to find side x
recall that the Pythagorean theorem states: 
In this case, a is 8, b is 8, and c is c
Now we can plug in the numbers and simplify.
