Study Notes
Algebraic Expressions
-
Definitions:
- Algebraic expression: a combination of variables, numbers, and operations
- Terms: individual parts of an expression separated by + or -
- Like terms: terms with the same variable and coefficient
-
Operations:
- Simplifying expressions: combining like terms
- Evaluating expressions: substituting values for variables
- Distributive property: expanding expressions using multiplication
-
Properties:
- Commutative property: order of variables does not change the result
- Associative property: order of operations does not change the result
- Distributive property: expanding expressions using multiplication
Inequalities
-
Definitions:
- Inequality: a statement comparing two expressions using >, <, ≥, or ≤
- Solution: a value that makes the inequality true
-
Operations:
- Adding or subtracting the same value to both sides
- Multiplying or dividing both sides by a positive value
- Flipping the inequality sign when multiplying or dividing by a negative value
-
Graphing:
- Number lines: visualizing inequalities on a number line
- Shaded regions: representing solutions on a number line
Quadratic Equations
-
Definitions:
- Quadratic equation: an equation of the form ax^2 + bx + c = 0
- Roots: solutions to the equation
-
Factoring:
- Factoring out the greatest common factor (GCF)
- Factoring quadratic expressions into (x + m)(x + n)
-
Quadratic Formula:
- x = (-b ± √(b^2 - 4ac)) / 2a
- Using the formula to find roots when factoring is not possible
Coordinate Geometry
-
Coordinate Plane:
- Quadrants: dividing the plane into four regions
- Axes: x-axis and y-axis
-
Points and Coordinates:
- Ordered pairs: (x, y) representing points on the plane
- Plotting points: graphing points on the coordinate plane
-
Graphing Lines:
- Slope-intercept form: y = mx + b
- Standard form: Ax + By = C
Data Analysis
-
Types of Data:
- Quantitative: numerical data
- Qualitative: categorical data
-
Measures of Central Tendency:
- Mean: average value
- Median: middle value
- Mode: most frequent value
-
Data Visualization:
- Histograms: displaying quantitative data
- Bar graphs: displaying categorical data
- Box plots: displaying summary statistics
Cebirsel İfadeler
-
Tanımlar:
- Cebirsel ifade: değişkenler, sayılar ve işlemlerin birleşmesi
- Terimler: + veya - ile ayrılmış ifade parçaları
- Benzer terimler: aynı değişken ve katsayılara sahip terimler
-
İşlemler:
- İfadelerin basitleştirilmesi: benzer terimlerin birleştirilmesi
- İfadelerin değerlendirilmesi: değişkenlere değer atama
- Dağıtım özelliği: çarpma kullanarak ifadelerin genişletilmesi
-
Özellikler:
- Değişim özelliği: değişkenlerin sırasının sonucu değiştirmemesi
- Birleşme özelliği: işlemlerin sırasının sonucu değiştirmemesi
- Dağıtım özelliği: çarpma kullanarak ifadelerin genişletilmesi
Eşitsizlikler
-
Tanımlar:
- Eşitsizlik: >, <, ≥, ≤ operatörleriyle iki ifadeyi karşılaştıran bir ifadedir
