Set up 2 different equations for each day and then solve using substitution or elimination
Answer:
Put a pretend dot at number 2 and number -4, then since the line is undefined, it will simply be vertical and look like this:
To find the rate of change, also known as the slope, we can use the slope formula with these two given points.
Point 1: (20, 25)
Point 2: (50, 40)
(40 - 25) / (50 - 20)
15 / 30
0.5
The rate of change of this function is $0.50 / lb.
Hope this helps!! :)
Geometry
This makes a cube because a cube has 6 faces, 8 vertices, and 12 edges.
