... Example 7 We need to rent a large truck for one week. Rental companies charge an initial cost plus an additional cost for each mile driven. One company, Paenz, will rent a 27 foot truck for us for $525 plus $0.21 per mile. Another company, Opan, will rent us the same size truck for $585 plus $0.13 ...

... Solving Linear Systems by Addition 1) If necessary, rewrite both equations in the form Ax + By = C. 2) If necessary, multiply either equation or both equations by appropriate nonzero numbers so that the sum of the x-coefficients or the sum of the ycoefficients is 0. 3) Add the equations in step 2.

BKL singularity
A BKL (Belinsky–Khalatnikov–Lifshitz) singularity is a model of the dynamic evolution of the Universe near the initial singularity, described by an anisotropic, homogeneous, chaotic solution to Einstein's field equations of gravitation. According to this model, the Universe is oscillating (expanding and contracting) around a singular point (singularity) in which time and space become equal to zero. This singularity is physically real in the sense that it is a necessary property of the solution, and will appear also in the exact solution of those equations. The singularity is not artificially created by the assumptions and simplifications made by the other well-known special solutions such as the Friedmann–Lemaître–Robertson–Walker, quasi-isotropic, and Kasner solutions.The Mixmaster universe is a solution to general relativity that exhibits properties similar to those discussed by BKL.
