Question 274697: ummm hi. My name is Rachel Smith. I am going to take the Alabama High School Graduation Exam on Monday for Algebra I. I don't remember anything from the previous semester. Can you help me? Can you give me some things I need to study? I am so nervous I don't know where to start.
Answer by JBarnum(2146) (Show Source): You can put this solution on YOUR website!
um for one thing u cant learn all of algebra 1 in 4 days
u must know how to do all of the following:
�� Evaluating variable expressions
where
�� Using the order of operations to simplify expressions
exponents, ( ), multiply, divide, add, subtract
�� Operations with signed numbers

�� The distributive property
and
�� Solving one step equations and Inequalities
a=5 b>-1
�� Solving multi-step equations and inequalities
a=8 b=1
�� Solving decimal equations
x=2
�� Using formulas
You need to read your book and find all the formulas including area, volume, quadratic,y-interceprt,slope etc.
�� Plotting Points on a coordinate system
review your book. (x,y) x-axis is left to right y-axis is up and down
�� Finding the slope of a line
m=slope (x1,y1)(x2,y2); (0,1)(1,0)
�� Graphing linear equations using slope-intercept form

�� Graphing linear equations using intercepts
review your book
�� Graphing horizontal and vertical lines
horizontal lines have the same value for y
verticle lines have the same value for x
�� Graphing inequalities
review your book has to do with a solid line if <=,>=
theres a dotted line for regular <,>
�� Using linear equations in real-life applications
you should have book examples
�� Writing an equation of a line using the slope-intercept form

�� Writing an equation of a line using the point-slope form
where m=3/4 and one point is (8,6)
�� Using the standard form of an equation of a line
�� Writing the equation of a line parallel or perpendicular to a given line
�� Solving a system of linear equations graphically
you should have book examples
�� Solving a system of linear equations using substitution
a+b=10 and a+2b=13 find a and b; a=10-b; 10-b+2b=13, b=3, a=7
�� Solving a system of linear equations using linear combinations
you should have book examples
�� Using systems of linear equations in real-life applications
you should have book examples
�� Evaluating exponential expressions
review book
�� Using the rules of exponents
multiplying by exponents means u add the exponents, divinding with exponents means u subtract exponents.

�� Using zero and negative exponents
any number to the 0th degree is 1. use a calculator for -exponents or review book
�� Finding the square root of an expression

�� Simplifying radical expressions
review in book
___
these below may or may not be in all algebra 1 courses:
i think its more for advanced algebra 1 or in algebra 2.
___
�� Adding and subtracting polynomials
�� Multiplying and dividing polynomials
�� Solving polynomial equations
�� Rate problems
�� Percent mixture problems
�� Work problems
�� Other types of word problems
�� Factoring trinomials with a leading coefficient of one
�� Factoring trinomials with a leading coefficient not equal to one
�� Factoring difference of squares
�� Factoring polynomials
�� Graphing a quadratic equation
�� Finding the roots of a quadratic equation
�� Graphing a quadratic equation
�� Solving a quadratic equation using the quadratic formula
�� Solving a quadratic equation by completing the square
�� Using the discriminant of a quadratic equation to determine its roots
�� Vertical motion application problems
�� Simplifying rational expressions by addition and subtraction
�� Simplifying rational expressions by multiplication and division
�� Solving rational equations
�� Exponential growth and decay
