<h2>Explanation:</h2>
When we say that an amount of something increases as another amount increases, at the same rate, then we are talking about Direct Proportion. It is also true for an amount of something that decreases as another amount decreases, at the same rate. So "y varies directly as x" can be written as:

In other words:

Where k is the constant of proportionality, and represents the slope of a line that passes through the origin.

Answer:
ABC & ADE You get these because of the line that separates the two triangles.
Answer:
10
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
9^2 + (sqrt(19))^2=c^2
81+19 = c^2
100 = c^2
Take the square root of each side
sqrt(100) = sqrt(c^2)
10 = c
The hypotenuse is 10
