Scribe of the Day.... Lena
Today is March 12, 2008
And in math class we learn about…
Explicit Formula's
Explicit Formula- Operation with linear equation involves multiplication/division or addition and subtraction
Today's Example:
0,3
1,5
2,7
3,9
4,11
x, 2x+3
The explicit Formula is- y=2x+3
TODAY'S TERM OF THE DAY
SLOPE
Slope= Rise/Run it represents the ratio of going from one point to the next.
Slope= y2-y1/x2-x1
Looks confusing right.... Well it's not
Just look at it this way...
0,3 is the starting point right
3 is your Y intercept
If X is Zero you can find your Y intercept by looking at the number
Slope=Intercept= intercept form
EASIEST WAY TO KNOW!!!!
y=mx+b
M=slope
B=y-intercept
Y=Intercept from
Here how we would graph it

S15/p11
MY PROBLEM.
All you have to do is distributive Property its just mostly multiplying what is inside the the parethesis and just do that
And that is it!

Simplfying Equations
Simplifying Expressions -Lena
An equation is simplified when all like terms are combined and parentheses have been removed.
Lena's Simplifying Expressions
Simplifying Expressions
1) Remove parentheses by multiplying factors (sorta Kinda like Distributive Properties when you take the parentheses and destroy them to make an equation with out parentheses).
2) Use exponent rules to remove parentheses in terms with exponents
3) Combine like terms by adding coefficients
4) Combine the constants
EXAMPLE
(first take of the parenteses of the equation)
10+5x+15x+12-(x^2)^2 (this is what it should look like now)
10+5x+15x+12-x^4 (Next you take the exponents and multiply them)
At this time you can take the terms you have and combined them!
(we will do the x's first you have to make sure that they match with the same ones)
10+20x+12-x^4 ( I combined the x' together because they were the same. I didnt combined it with the other x because even though they have the same variable they have to different things that make them different)
22+20x-x^4 ( I combined the next one as well just like how I did in the previous one)
Your done! But to make it perfect in Simplifying Equations you must make sure that it is in a certian order. You put it in You start with the largest Exponent and work your way down UNTIL you get down to the end.
-x^4+20x+22)
Thats how you simplfy an equation!
