..two integers √41 lies between… *to find an answer… Back Side of Flash Card Choose a perfect square SMALLER and BIGGER than 41 The square root of both #’s is the answer

Front Side of Flash Card Decimal to Percent Percent to Decimal
Back Side of Flash Card DP : move decimal 2 spaces RIGHT PD : move decimal 2 spaces LEFT

Front Side of Flash Card Probability of multiple coin flips
Back Side of Flash Card Multiply probabilities each coin flip

Front Side of Flash Card Increase by a scale factor #
Back Side of Flash Card Means you multiply original value by factor #

Front Side of Flash Card Parallel Slopes Perpendicular Slopes
Back Side of Flash Card Both lines have the same slope. Both slopes are the OPPOSITE RECIPROCAL of each other

Front Side of Flash Card What is the best test-taking strategy?
Back Side of Flash Card TAKE YOUR TIME, GO SLOWLY, AND DON’T OVER-THINK THE PROBLEM!!1!

Front Side of Flash Card
Calculating % commission of a price (total commission) Back Side of Flash Card Convert % to decimal Multiply that by the price

Front Side of Flash Card Properties of parallelograms
Back Side of Flash Card 2 parallel sides with the same length 2 other sides that have the same length (usually at an angle)

Front Side of Flash Card Calculating the y-intercept
Back Side of Flash Card Plug in 0 for x and then solve for y. Answer: ( 0 , )

Front Side of Flash Card
What is the equation of a line when given point and slope? Back Side of Flash Card Use the point-slope formula: Plug in values and solve for y.

Front Side of Flash Card Graph y=x^2
Back Side of Flash Card x^2 is a parabola facing upwards Positive coefficient

Front Side of Flash Card Graph y = -x^2
Back Side of Flash Card -x^2 is a parabola facing downwards Negative coefficient

Front Side of Flash Card Graph y = -x^3 Cubic Function
Back Side of Flash Card S-shaped graph Looks like negative slope

Front Side of Flash Card Graph y = x^3 Cubic Function
Back Side of Flash Card S-shaped graph Looks like positive slope

…vehicle traveling at a certain speed… …distance against the wind, and greater distance with the wind… Back Side of Flash Card Use rt=d formula Wind will be added and subtracted from original speed

Front Side of Flash Card Polygon Similarity
Back Side of Flash Card Polygons need to have the same angles Segment lengths must be in proportion to each other

Front Side of Flash Card Polygon Congruence
Back Side of Flash Card Polygons need to have the same angles Segment lengths need to be the same

Front Side of Flash Card Calc. missing length of a triangle:
Back Side of Flash Card Pythagorean Theorem Triangle needs to have 90* box Hypotenuse (c) opposite 90* box

Front Side of Flash Card Solving SYSTEMS of linear equations
Back Side of Flash Card Plug in x and y values to both equations. Correct answer when both sides equal 5 = 5

Front Side of Flash Card Negative exponents… what do you do??
Back Side of Flash Card Reciprocal the number Make the exponent positive Simplify

Front Side of Flash Card Dividing same base exponents
Back Side of Flash Card Subtract exponents Upstairs guy minus downstairs guy Reciprocal any negative exponents

Front Side of Flash Card Exponents outside the parenthesis
Back Side of Flash Card Exponents multiply Coefficients and some variables have an invisible 1 exp.

Front Side of Flash Card Mean
Back Side of Flash Card Average Add up all data points and divide by # of points

Front Side of Flash Card Median
Back Side of Flash Card Line up all data points (smallest to largest) Pick the guy in the middle (find the mean if there are 2 in the middle)

Front Side of Flash Card Mode Modal
Back Side of Flash Card # in a data set that you see most often {1, 2, 2, 3, 2} mode=2
