Explanation Given: Equation y ( y − 2 ) = − 1 Formula Used : Discriminant for standard form a x 2 + b x + c = 0 is given by D = b 2 − 4 a c Calculations: Consider Equation y ( y − 2 ) = − 1 The equation can be written as y 2 − 2 y + 1 = 0 Now compare the standard form a x 2 + b x + c = 0 with equation y 2 − 2 y + 1 = 0 we get, a = 1 ; b = − 2 ; c = 1 Now, Discriminant is given by D = b 2 − 4 a c , therefore &e

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.

Three streams - Stream A, Stream B, and Stream C - flow into a lake. The flow rates of these streams are not yet known and thus to be found. The combined water inflow from the streams is 300 m³/h. The rate of Stream A is three times the combined rates of Stream B and Stream C. The rate of Stream B is 50 m³/h less than half of the difference between the rates of Stream A and Stream C. Find the flow rates of the three streams by setting up an equation system Ax = b and solving it for x. Provide the values of A and b. Assuming that you get to an upper-triangular matrix U using an elimination matrix E such that U = E A, provide also the components of E.
