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
