Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
suppose a cup of hot cocoa cooled from 90 degrees Celsius to 60 degrees Celsius after 10 minutes in a room whose temperature was 20 degrees celsius. use newton's law of cooling to find how much longer it will take for the cocoa to cool to 35 degrees celsius
