Flashcards in Number Properties Deck (6)
When working with inequalities where the product of 2+ variables is compared to 0...
...remove the even powered terms to simplify the expression
Z^2(y) < 0 becomes y<0
To take the distance between two points
Take the absolute value of their difference
(Distance between -4 and 5 = |-4-5| = |-9| = 9
To solve the distance between 2 points that involve intervals with even numbers
Distance/ Number of intervalos = Length of interval
Number of tick marks in relation to intervals (on a number line)
Number of tick marks will always be 1 greater than number of intervals
If the order of points on a number line is not mentioned...
...do not assume a specific order,
(Could be A, B, C, could be A, C, B, etc.)
