The following is known about three numbers: If the second number is subtracted from the sum of the first number and 5 times the third number, the result is -6. The third number plus 2 times the first number is -1. The first number plus 5 times the second number plus the third number is 4. Find the three numbers. [Hint: let x represent the first number, y the second number, and z the third number. Use the given conditions to write and solve a system of equations.]
Quadratic Equation
When it comes to the concept of polynomial equations, quadratic equations can be said to be a special case. What does solving a quadratic equation mean? We will understand the quadratics and their types once we are familiar with the polynomial equations and their types.
Demand and Supply Function
The concept of demand and supply is important for various factors. One of them is studying and evaluating the condition of an economy within a given period of time. The analysis or evaluation of the demand side factors are important for the suppliers to understand the consumer behavior. The evaluation of supply side factors is important for the consumers in order to understand that what kind of combination of goods or what kind of goods and services he or she should consume in order to maximize his utility and minimize the cost. Therefore, in microeconomics both of these concepts are extremely important in order to have an idea that what exactly is going on in the economy.
