Absolute values In an absolute value‚ everything with it is counted as a positive. ∣-a∣ = --a= a ∣a∣ =a In an equation‚ absolute values have two possibilities when talking about equations ∣a+b∣ =x = a+b=x = a+b= -x e.g. Solve ∣x-4∣=8 x-4=8 OR x-4= -8 x=12 x=-4 Sub both answer into the equation ∣12-4∣ =8 OR ∣-4-4∣ =8 8=8 8=8 Both solution re true so x=12 or x=-4 Absolute inequalities (method 1) If ∣a+b∣ ≤x∣a+b∣

point average. Systems of linear equations‚ or a set of equations with two or more variables‚ are an essential part of finding solutions with only limited information‚ which happens to be exactly what algebra is. As a required part of any algebra student’s life‚ it is best to understand how they work‚ not only so an acceptable grade is received‚ but also so one day the systems can be used to actually find desired information with ease. There are three main methods of defining a system of linear equations

Checkpoint Week 8 John McManamon IRN: 9048277815 IT/205 4/16/2014 John Gosney 1. How important is the reservation system at airlines such as WestJet and JetBlue? How does it impact operational activities and decision making? As an employee of an oil company‚ I am keenly aware that the price of gulf coast kerosene (jet fuel) is almost $3.00 per gallon. With an estimated 30‚000 flights per day in the US alone‚ there is a tremendous amount of money spent by planes idling at the gate‚ or on
