11.2 Direct and Inverse Variation Goal: Use direct and inverse variation
Standard 13.0 Students add, subtract, multiply, and divide rational expressions and functions. Students solve both computationally and conceptually challenging problems by using these techniques. Los estudiantes suman, restan, multiplican, y dividen expresiones y funciones racionales. Los estudiantes solucionan problemas desafiadores computacionalmente y conceptualmente usando estas técnicas.
Direct Variation The variables x and y vary directly if for a constant k Or y = kx, where k 0
Indirect Variation The variables x and y vary inversely if for a constant k xy = k Or where k 0 The number k is the constant of variation
