Answer:
I think it's D. The independent variable is the length of the race. The dependent variable is the time.
Step-by-step explanation:
Here I'm quoting user kaylaj051903 "because an independent variable is something that is constant and does not change throughout the problem. The dependent variable depends on the independent variable. The race is a 5K race. That will not change. What will change is how long it takes Stephanie to run the 5K race."
Answer:
(0,10)
Step-by-step explanation:
-x + 2y = 20
2y = x +20
y = 1/2x + 10
This is slope-intercept form. The y-intercept is 10.

Answer: 19.8 Units
Step-by-step explanation:
The triangle is shown in the attached figure, and have three vertices: 
, 
and 
.
Each vertice represents a point in the cartesian plane and the length of each side of the triangle is the modulus of each vector.
In this sense, the modulus 
is calculated as shown:
Hence, for each vector:
Now, the perimeter of a triangle is the sum of its three sides:
Finally:
