Answer:
B.
Step-by-step explanation:
If you want to find a table with a proportional relationship, you are looking for one where the x-values and y-values increase at the same linear rate.
In Option A, the x-values increase steadily by 1 and then by 2, but the y-values jump around. The numbers are not proportional.
In Option B, every time an x-value is presented, the y-value is two times the value of x. So, this is a proportional relationship.
In Option C, it is true that for almost every time an x-value is presented, the y-value doubles the x-value, but when x is 0, y is 1. That is not a proportional relationship.
In Option D, it is the same thing as Option A.
So, your answer is Option B.

Answer:
x = 5
Step-by-step explanation:
Since these are similar triangles all you need to do is figure out how much "x" has gotten smaller.
First take the line DE length (16) and divide it by line BC (8)
16 / 8 = 2
Now divide line BD by 2
10 / 2 = 5
x = 5
