Suggest two other models of quantitative relationships other than time and work, and distance and time?

2. (i) Explain the difference between a constant and a variable. (ii) Explain the difference between a constant and a coefficient. (iii) Explain the difference between a term and a factor. Use examples to support your explanations.Suggest two other models of quantitative relationships other than time and work, and distance and time?
The term 'constant' refers to the unchanging 'value' - simply put how far along the number line the 'number' is from zero it represents,while a variable is like a folder which can hold any value according to the directions contained in an equation; a co-efficient attaches itself to a variable like a disgusting,toxin-filled tick and influences the value which the variable becomes after all calculations are done; the variable 'turns into' a value,then the co-efficient does its thing to it.


A factor - derived from the Latin 'to do' - is a constant or variable which influences one or more other constants or variables - often via the Distributive Law'. . . like if you had to simplify 3x + 2xy the factor here would be 'x' i.e., x(3 + 2y) as for the other.question . .how about the relationship b/w power and work. . .or Area and the difference b/w the sides ( its a parabola ! )
