Math Study Guide Chapters Chapter 1 Algorithm measuring rod by whole tone directions Ex. Algorithm to Solve discrepancy Distribute 7-5(x+6) > 32 Combine like impairment 7-5x-30 > 22 Eliminate #s on the left side (-5)x-23 > 32 (add 23 to some(prenominal) sides) Combine like terms (-5)x-23+23>32+32 tell both sides by co-efficient (-5)x > 55 x < 11 |________|________ -11 0 Loop in algorithmic program A specify where the process might have you re-do steps. basis to know: superlative Common Factor(GCF)- The largest number that factors evenly into devil or much larger numbers. Ex. 12 is the largest number that pull up bet divide evenly into 36 & 48 Least earthy denominator(LCD)- The net common muliple of the denominator of both or more fractions. Ex. N M = 144 3648 * Then sum of the lengths of any two sides of a triangle is greater than the length of the 3rd side. Ex.

3 6 10 = not a triangle 4 7 9 = triangle Box and Whisker Plots- a way to diagrammatically show stats Plots show: naturals Med ian Quartile #s Test Scores 26, 28, 34,! 34, 38, 40, 41, 44, 44, 44, 46, 48, 49 cast down Extreme Lower Median Upper Upper Extreme Quartile Quartile Systems of equating 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 re-sentencing Elimination Matrices Ex. intercellular substance 3x-7y=21 2 1 x...If you want to get a full essay, order it on our website: BestEssayCheap.com
