He didn't do it as rise over run, or y2-y1/x2-x1
He did it reverse, which is incorrect.
It's obvious that every normal person has ten fingers. Since we have ten fingers, our numbering is based on multiples of ten which is called decimal. Can you imagine how life would be different if all human beings were born with eight fingers instead of ten? Maybe our numbering system would be based on multiples of eight.

Answer:
C delta notation change in y over chance in x
One cubic centimeter is 1 mL. 1000 cubic centimeters is 1 liter. 525 cm3 is .525 liters.
Answer:

Step-by-step explanation:
Given the literal equation, y = 5x - rx - 5,
In order to solve for x, start by adding 5 on both sides of the equation:
y + 5 = 5x - rx - 5 + 5
y + 5 = 5x - rx
Next, factor out x from the right-hand side of the equation:
y + 5 = x(5 - r)
Finally, divide both sides by (5 - r) to isolate x:
