Trichotomy law only three possible relationships between X & Y, X Y Y X X =Y Multiplicative property of equality Multiplying/ Dividing the same value to each side of the equation 4X=8 X=2 Zero Product Property Set quadratic equal to zero, factor and solve for each factor. (X-3)(X-4) X-3=0 X-4=0 Additive Property of equality Adding the same number to both sides X+2=10 X+2-2=10-2 Substitution Property Substituting a value for numbers 2(a+b)=3 a+b=9 2(a)=3C Symmetric Property Only Switching sides 10=Y Y=10 Reflexive Property Anything equaling itself 7Y=7Y Multiplicative Identity Multiplied and didn't change anything 5X1=5 Additive Identity The sum of any number and zero is the original number 5+0=0 Distributive Property Multiplying through a parenthesis a(a+b)=ab+ac Associative Property Regrouping a+(b+c)= (a+b)+c Commutative Property Move Around a+b=b+a ab=ba Factors Numbers you can multiply together to get another number. Composite Number A whole number that can be divided by numbers other than 1 and itself. Prime Number A whole greater than 1 whose only 2 whole factors are 1 and itself. How to find the probability of an event Fraction: Number of favorable outcomes possible __________________________________________ Total possible outcomes Percent Increase formula Fraction: Difference between percents _______________________________ X 100= % Increase Starting Point Median Middle value No middle, take average of two middle values. Median is in the middle of the freeway. Range Difference between highest and lowest values Mode Value that happens most frequently The most frequently used mode of transportation is a car. Mean Average Don't be mean because you're average. If a line joining 2 points is vertical the slope is Undefined or no slope Slope Formula (Y2-Y1) _______ (X2-X1) If a line joining 2 points is horizontal the slope is: Zero If a line joining 2 points goes down and to the right the slope is Negative If a line joining 2 points goes up and to the right the slope is Positive Slope Definition Vertical change/ Horizontal Change Rise/Run Algebraic elimination method Either add/subtract the same number to each equation to eliminate a variable. Radius Half the diameter Distance from center of circle to the circle. Diameter Length of the circle from edge to edge. Area of a circle A=πr² π Value 3.14 Integer Whole number not a fraction or fractional component Rational Number Ratio=Fraction Can be positive or negative Least Common Multiple Comparing 2 values Multiply each value to find the smallest value they have in common. Additive Inverse Property A value when added to any number = 0 1+(-1)=0 Opposite of number Identity numbers Property A value when added/multiplied to another number doesn't change the value. Addition = 0 3+0=3 Multiplication = 1 3X1=3 Distributive Property Multiplying through parenthesis Multiplication outside parenthesis distributed over either add/sub inside parenthesis. 3(5+2) = 3(5)+3(2) Associative Property Regrouping in same order 8+(4+2)=(8+4)+2 Not division or multiplication Commutative Property Commute-move around The order in which add/mult is done and doesn't effect answer. a+b=b+a aXb=bXa Can't be subtraction or division What are the metric terms in order smallest to largest milli= 1/1000 centi= 1/100 deci= 1/10 meter/liter/gram = 1 deca= 10 hecto=100 kilo=1000 1 bushel = how many peck 4 pecks 1 gallon = how many quarts 4 quarts 1 quart = how many pints 2 pints 1 pint = how many cups 2 cups 1 ton = how many pounds 2,000 pounds 1 mile = how many feet 5280 feet 1 mile = how many yards 1760 yards Composite Number Not a prime number composed of multiples Prime Number Number who only has 1 and itself and multiples Real Number All the rational and irrational numbers
