Joint Variation and Direct Variation

Direct variation = with two or more variables Inverse variation = with two variables Combined variation = with three variables

a = kb/c = where k is the constant of variation a = k/bc = where k is the constant of variation a = kbc = where k is the constant of variation a = bc/k = where k is the constant of variation

the variable of variation = a the product of b and c = bc the constant of variation = k the ratio of a to bc = a/bc

<p>k = a/bc = where a, b, and c are the variables k = a/b + c = where a, b, and c are the variables k = abc = where a, b, and c are the variables k = a - bc = where a, b, and c are the variables</p> Signup and view all the answers

<p>a is inversely proportional to bc = a = k/bc a is directly proportional to bc = a = kbc a is directly proportional to b and inversely proportional to c = a = kb/c a is inversely proportional to b and directly proportional to c = a = c/kb</p> Signup and view all the answers
