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
x%2B4=5 where x=1
�� Using the order of operations to simplify expressions
exponents, ( ), multiply, divide, add, subtract
�� Operations with signed numbers
-6-5%284-7%29=4
�� The distributive property
5%28x%2B4%29=5x%2B20 and %28x%2B4%29%28x-4%29=x%5E2-16
�� Solving one step equations and Inequalities
a%2B5=10 a=5 b%2B6%3E5 b>-1
�� Solving multi-step equations and inequalities
%283a%2B4%29%2F2=10 a=8 2%285b-7%29%3C=6 b=1
�� Solving decimal equations
.25%284%29%2B.50x=2 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=%28y2-y1%29%2F%28x2-x1%29 m=slope (x1,y1)(x2,y2); (0,1)(1,0)
�� Graphing linear equations using slope-intercept form
y=mx%2Bb
�� Graphing linear equations using intercepts
y=mx%2Bb 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
y=3x%2B7
�� Writing an equation of a line using the point-slope form
3%2F4=%286-y%29%2F%288-x%29 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. %28x%5E3%29%28x%5E5%29=x%5E8%28y%5E9%29%2F%28y%5E3%29=y%5E6
�� Using zero and negative exponents
any number to the 0th degree is 1. 1%5E0=11456798436%5E0=1 use a calculator for -exponents or review book
�� Finding the square root of an expression
sqrt%28x%5E2%29=x sqrt%28x%5E4%29=x%5E2 sqrt%28x%5E10%29=x%5E5 x%5E10=x%5E5%28x%5E5%29
�� Simplifying radical expressions
