Math Study Guide Chapters Chapter 1 recursive program Step by total tone directions Ex. Algorithm to work out Inequality Distribute 7-5(x+6) > 32 Combine desire impairment 7-5x-30 > 22 Eliminate #s on the left berth (-5)x-23 > 32 (add 23 to some(prenominal) sides) Combine kindred terms (-5)x-23+23>32+32 Divide some(prenominal) sides by co-efficient (-5)x > 55 x < 11 |________|________ -11 0 Loop in algorithmic program A attribute where the process might father you re-do steps. basis to know: superlative Common Factor(GCF)- The largest phone number that factors evenly into devil or much larger numbers. Ex. 12 is the largest number that pull up interest divide evenly into 36 & 48 Least common denominator(LCD)- The wage common muliple of the denominator of two or more fractions. Ex. N M = 144 3648 * Then sum of the lengths of whatever two sides of a trigon is greater than the length of the tertiary side. Ex.

3 6 10 = not a trilateral 4 7 9 = triangle Box and Whisker Plots- a way to diagrammatically institute stats Plots show: Extremes Median Quartile #s Test Scores 26, 28, 34, 34, 38, 40, 41, 44, 44, 44, 46, 48, 49 drag down Extreme demoralize Median upper Upper Extreme Quartile Quartile Systems of Equation y = mx+b m = slope b = where it crosses y axis Ex. 2x+y = 7  y = 2x+7 Ex. 3x+4y = 12  - 4y = -3x+12 y = 3/4x-3 Methods of solving: Graphing Substitution Elimination Matrices Ex. intercellular substance 3x-7y=21 2 1 x...If you want to beat a full essay, regularise it on our website: Orderessay
