Linear Inequalities in One Variable
This lesson covers linear inequalities in one variable. It includes identifying, solving, and representing solutions of linear inequalities on a number line. Word problems involving linear inequalities are also addressed.
- 26:28 “like this, take note that the sign can change if it is division, okay, thank you very much for watching, my name is Oyase Sunday, till next time.”
- 01:34 “be concentrating on one variable, representing solution of linear inequality in one variable on a number line, and solve what problem involving linear inequality in one variable. So, all our attention here will be direct...”
- 23:00 “easy, what do you do, find the LCD, what are the LCDs there, find the LCD, the I's, which is what, 2x, LCDs, and that's what, 2x, so, use the multiplicative inverse for everything or 2, so I will have what, 2x multiply b...”
Simplification of Algebraic Expressions
This lesson covers the definition of algebraic expressions and their components, including terms and coefficients. It explains how to identify like terms, perform arithmetic operations on similar terms, and simplify expressions by inserting or removing brackets.
- 01:36 “Here we deal with alphabets majorly, such as X or Y to represent the unknown values. Here are some examples of algebraic expressions. We have two X plus 10 Y plus one. You can note that it does not have an equal sign. Wh...”
- 08:01 “But now we are talking about constants and coefficients. What is a constant? What is a coefficient? In this expression, five is a constant. How is it a constant? Because it does not change its value. It continues to be f...”
- 11:12 “How many terms do we have here? We have one, two, three, four. Why do we have y as part of the terms? Because, of course, we have an invisible one here. So it doesn't stand on its own. Remember, I told you a term can jus...”
Cost of Production
This lesson covers the concept of cost in economics, focusing on the cost of production. It explains different types of costs, such as fixed and variable costs, and discusses the factors of production that contribute to overall costs.
- 16:04 “you calculate your worth, your total cost, please take note, your total cost here is going to be worth, it's going to be fixed cost, plus worth, plus variable cost, okay, remember the first one I get to you is worth, is...”
- 12:54 “So this is how you draw the graph, it's very simple, first cost is set to be worth, it's set to be horizontal to the x-axis, are we together, it's not more than that, okay? Then let's move to the next one, please, and th...”
- 14:26 “to incur more costs for it to get a better worth service, than the cost of where as well. The cost of field is another good example of worth of a variable cost, and your variable cost, what is the graph, look at the boar...”
