Exam Guide For Algebra I 1st Semester 2008 Remember it is 20% of your grade for first semester.

Schedule for Exams are as follows:

Monday, January 21 is a holiday so STUDY FOR ALL EXAMS

Tuesday, January 22: 1st and 2nd periods 8:45 and 11:00 dismissed at 1:00

Wednesday, January 23: 3rd and 4th 8:45 and 11:00 dismissed at 1:00

Thursday, January 24: 6th and 7th 8:45 and 11:00 dismissed at 1:00

Friday, January 25: 5th and you are dismissed at 10:40

The exams are 20% of your semester grade which is the same as half of a 9 weeks grade:

Here is how to compute your averages: 1st 9 40%, 2nd 9 weeks 40%, Exam 20%

Example: Joe Bob's grades are 1st 9 wks 82%, 2nd 9 wks 90%, Exam 89%

Here is how you find semester average: Then add the 3 amounts

So Joe-Bob's grade is 86.6% or 87%

Here is what to study for this Algebra I exam.

Chapter 1: Expressions, equations, properties, order of operations

  • Verbal expression to algebraic expression: the sum of a number and 21> x + 21
  • Number patterns: give next three numbers: 2,4,8,16,__, ___, ___
  • Evaluate expression: Find 2xy + if x = 5, y=2, b=3 Plug in numbers and do math
  • Order of operations PEMDAS left to right
  • Properties: page 37-39, 52
  • Stem and Leaf Plot

Chapter 2 :Integers and fractions and decimals Be able to add, subtract, multiply, divide

  • Graph on a number line like x > 2
  • Know your rules for positive and negative numbers
  • Add, subtract fractions get a LCD
  • Multiply fractions, cross-reduce
  • Divide fractions, use the reciprocal and cross-reduce
  • Compare two numbers using <, >, or = ex. -8_____
  • Absolute Value of numbers

Chapter 3 : Solve Linear Equations

  • Be able to solve a 4- step equation
  • 1st Step use distributive property, get rid of ( )
  • ex.
  • 2nd step Add/ Combine Like terms on same side only of =
  • 5x + 6x = 11x
  • 3rd Step: Add or Subtract on both sides to get the variable to one side and number to other *** DO OPPOSITE OPERATION Here*
  • 4th Step: Multiply or divide by the coefficient of x to isolate it
  • Word Problems and Consecutive Integers Problems
  • EX. Find 4 consecutive integers whose sum is 130.

Chapter 4: Proportions, Percents, % of Change, Probability/Odds Direct and Inverse Variation

  • Ratios, Proportions Cross-Multiply
  • Percent problems % to a decimal, of means to multiply
  • Is means" =" Ex. 28 is 35% of what numbers?
  • Use What number is 60% of 80?
  • Sales Tax, Discount of a price % of increase,decrease
  • Odds or Probability P =
  • Odds =
  • Direct or Inverse Variation pg 240-241

Chapter 5: Domain, range, inverse, functions, graphs

  • Ordered Pairs, Quadrants, (x,y)
  • Domain (x), range (y), Inverse (y,x)
  • Functions: Where x does not repeat,
  • Vertical line test for functions
  • Find value of f ( x) by plugging in a number for x
  • Graphs of linear equations

Chapter 6 Slope, Lines, Equations of lines, parallel and perpendicular lines

  • Slope using
  • Ax + By = C
  • Y = mx + b
  • Graphing lines HOY-VUX,
  • Find slope, x and y-intercepts
  • Determine if lines are parallel, perpendicular, or neither by comparing slopes
  • Ax + By = C slope is , x-intercept cover y-term, y-intercept cover x-term

Be able to graph lines, determine the slope of a line and the y intercept of a line when given a line

How to study: 1st Review old test and bring the tests with you on the day of the exam for extra credit; 1 point for each test

2nd: On my web page under exam review days are practice test from each chapter do these

3rd. Look over the chapter reviews from the first 6 chapters in book

4th: Study and review on Monday for all of your exams*****

  1. Study over the weekend but take time off Sunday at 3:00 pm to watch the World Champion New England Patriots beat up on the Chargers from some city in California that used to be part of Mexico. Watch perfection and what trying hard and practicing hard will do for you. Remember that Tom Brady was home studying game film while Tony Romo (0-2) in playoffs was off to Cancun with a part-time Hollywood starlight. So now the Cowgirls are home watching TV this Sunday while the 17-0 NEW ENGLAND PATRIOTS are playing another game!!!!!!!!!!!!! On their way to perfection.
