This includes independent variables‚ dependent variables and graphic solutions of these inequalities although graphs can express many different possibilities of answers. In this week’s assignment‚ number 68 on page 539 in our text Elementary and Intermediate Algebra (Dugopolski‚ 2012) is our given problem. The graph below is similar to the one in our text. It shows all of the possibilities of refrigerators and TVs that will fit into an 18-wheeler. A shipping container can carry maximum of 110 refrigerators

Example: y = 2x+1 is a linear equation: The graph of y = 2x+1 is a straight line When x increases‚ y increases twice as fast‚ hence 2x When x is 0‚ y is already 1. Hence +1 is also needed So: y = 2x + 1 Here are some example values: http://www.mathsisfun.com/algebra/linear-equations.html x y = 2x + 1 1 y = 2 × (1) + 1 = 1 0 y = 2 × 0 + 1 = 1 1 y = 2 × 1 + 1 = 3 1/6 2014/9/16 Linear Equations 2 y = 2 × 2 + 1 = 5 Check for yourself that those points are part of the line above!

Quadratic Equations Equations Quadratic MODULE - I Algebra 2 Notes QUADRATIC EQUATIONS Recall that an algebraic equation of the second degree is written in general form as ax 2 + bx + c = 0‚ a ≠ 0 It is called a quadratic equation in x. The coefficient ‘a’ is the first or leading coefficient‚ ‘b’ is the second or middle coefficient and ‘c’ is the constant term (or third coefficient). For example‚ 7x² + 2x + 5 = 0‚ 5 1 x² + x + 1 = 0‚ 2 2 1 = 0‚ 2 x² + 7x = 0‚ are all

COMMUNITISATION CONCEPTUAL FRAMEWORK: The concept of communitisation is about substantially improving the quality and delivery of public services such as the elementary school at the grass roots by harnessing the age-old social capital availability in the community. A system of communitisation as it were thus represents a parading shift from the model of government where authority lies wholly in the hands of the government. Its defining characteristic is a unique partnership involving
