Chapter 2: Graphs, Functions, and Linear Equations

Graphs are an important part of Algebra since they allow us to visualize information from the equations of Algebra.  After all, we deal better with the visual than the equation.  When we have an equation of two variables, we can see how they relate to one another more readily in a graph than in an equation.


The course of Algebra focuses on the concept of functions (which will be defined in Section 2; because yes, functions are different than equations).  Most of the graphs considered here are what is called linear equations, equations which produce lines.  This chapter has the purpose of not only teaching the basics of graphing functions, but also using them for problem solving.

That's the end of this section.  If you have any questions, please leave them is the comments.  Like and share this post if you found it helpful.  And until next time, stay curious.

General Chemistry 1 Section 1.3: Properties of Matter

Hello internet, and welcome to the Science of Life General Chemistry lecture series.  In this session, I'll cover some of the properties of the materials in which chemists are interested. Properties There are two types of properties which we deal with in General Chemistry.  There are more types, but there are specifically two that are important for this course.  There are physical properties (properties which do not describe the chemistry of the substance, such as the phase) and chemical properties (which do describe the chemistry of the substance, such as whether or not it's an acid).  Properties can also be classed as either extrinsic (depends on the quantity of the substance, such as the mass) or intrinsic (does not depend on the quantity, such as melting point).  Boiling point is an intrinsic physical property; it doesn't describe the chemistry of the substance (alas the physical part) and the boiling point at that pressure doesn't change with quantity of sub

Systems of Equations in Two Variables - Chapter 3 Section 1

Typically, problems involving at least two unknowns are solved by translating the problem to two or more equations, such as the slope-intercept form and/or the standard form of the line. Developing Equations from Sentence Form When deciphering word problems, we typically try to take a word or phrase which explains what a variable is and represent that word or phrase as a single letter instead. For instance, the energy consumed by your household so far this billing cycle can be represented by the letter E, and the total cost so far in that pay cycle can be represented by the letter C. It is also useful to translate commonly used words into mathematical operations. For example, the product of two things m and c represents multiplication, while the square of c represents squaring the letter c. So the product of the two values of m and the square of c would be $m \times c^2$. I will leave a table of some common and uncommon phrases and their mathematical translations here . Outs

Algebra Chapter 1 Section 7: Scientific Notation

In science, there are many numbers which are either exceedingly large (for example, the number of water molecules in a liter of water) or exceedingly small (for example, the charge, in Coulombs, of a single electron).  This is the nature of the reality we live in.  This is why, in some cases, it is easier to read and right these extremely small and large values in a more compact notation.  Yes, this does somewhat reduce accuracy, but the loss of accuracy has very little baring on the accuracy of the final answer.  The most common compact notation in Social Sciences, Life Sciences, and Physical Sciences is called Scientific Notation . The notation for Scientific Notation is $N \times 10^{n}$, where N is a number which is at least 1 but less than 10 $[1 \le N < 10]$ and n is the magnitude of the number.  There are a couple steps to convert to scientific notation: Place a decimal point in between the first two significant digits of the number. Find the magnitude by determining
