Proportionality, assuming constant rate. 460 dives/12 hours = x dives/3 hours. Solve for x.
The answer is probably 2 because if you plug in the numbers you would get
3x-4=-12 divided by -6 = +2.
Answer:
3
Step-by-step explanation:
First, find the midline by averaging the highest value (2) and the lowest value (-4). In other words, do (2+-4)/2. You get the midline as -1. Now find the distance from the midline to the top. Distance from -1 to 2 is 3. Amplitude is therefore 3.
Slope of 40x + 15000: m = 40
