If and y are variable quantities such that y=k/x for some consranr k, then we say that y is inversely proportional to x. That is, k/x increases , y decreases. Inverse proportionality may also be expressed by xy = x or x1*y1 = x2*y2 Use this fact to solve: 4. x and y are two variables known to be inversely proportional to each other whose previous values were each 2. x now decreases to 1. What is the new value of y?
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.
