The y-intercept is the point at which a linear equation crosses the y-axis on the x=0 plot point. The equation to determine both the slope and the y-intercept of a line is y=mx+b. This calculation may ...

Often the questions we ask require us to make accurate predictions on how one factor affects an outcome. If a teacher is asked to work out how time spent writing an essay affects essay grades, it’s ...

Make sure you are confident in calculating with negative numbers, which is a skill often needed to solve equations. To solve the equation, do the inverse operation. The inverse of multiplying by 12 is ...

Introduces ordinary differential equations, systems of linear equations, matrices, determinants, vector spaces, linear transformations, and systems of linear differential equations. Prereq., APPM 1360 ...

Mathematics of Computation, Vol. 32, No. 144 (Oct., 1978), pp. 1183-1213 (31 pages) This paper furnishes two classes of methods for calculating the best approximate solution of an operator equation in ...

Consumer surplus is the amount exceeding an equilibrium price the consumer is willing to pay. The equilibrium price is an idealized price, in which the demand for the good equals its supply. If the ...

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...
