It is the likeliness of an event happening based on all the POSSIBLE outcomes.
Based on an experiment written as a ratio comparing the number of times the event occurred to the number of trials.
A polynomial which is written in decreasing order by degree where all like terms have been combined.
y = kx, Increase (or decrease) in one variable causes a proportional increase (or decrease) in another variable
y = k/x, As one quantity increases, the other quantity decreases
y = kxz, a relationship that occurs when a quantity varies directly with the product of two or more other quantities
A property indicating a special way in which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses, such as a(b + c) = ab + ac
The property that states that two or more numbers can be added/multiplied in any order without changing the sum/product.
The property that states changing the grouping of numbers will NOT change the value. For example: (7 + 4) + 8 = 7 + (4 + 8) also works with multiplication
An expression that contains a radical. It must be reduced to simplest terms by prime factorization and then removing appropriately paired factors.
System of Linear Equations
Two or more linear equations for which you can solve for the missing variables.
Two inequalities that are combined into one statement by the word AND or OR.
A compound statement formed by joining two or more statements with the word OR
A compound statement formed by joining two or more statements with the word AND
Slopes are opposite reciprocals. One solution. Consistent/Independent
Slopes are the same but y-intercepts must be different. No solution. Inconsistent
Slopes are different. One solution. Consistent/Independent
Slopes and y-intercepts are the same. Infinitely many solutions. Consistent/Dependent
Factor an expression
To break an expression down into prime factors.
Types of factoring
GCF - Greatest Common Factor DOTS - Difference of two squares PST - Perfect Square trinomial Grouping - Four or more terms General - What multiplies to give ac but adds to give b then reduce
Factor the GCF
Greatest Common Factor Ex: 4x - 8 = 4(x - 2)
Difference of two squares Ex: x² - 4 = (x + 2) ( x - 2)
