* To solve an exponential equation, express both sides as powers with the same base and let the exponents equal each other.
eg. 9x+1= 27
this is what we did in class today and h/w is Ex #26 (omit 8,9,12,15 & 19)
and tomorrow is halloween and if you come to class with costume you'll get candy and we have quiz on // and I and on the number of sets .
tomorrows scribe is PAULO
Example#2:and are both rational because the 1st number repeats and the 2nd number terminates.
However, 7.23242526.......... -- > is not a rational number because the number does not repeat or terminate. This is an example of irrational number because the number never ends.
Irrational Numbers ---> a number that cannot be put in the form of a/b where a,b is an element of Integers.
However, the decimal form of an irrational number will never end or repeat.
Don't forget to do your Homework!
Explain how to solve each of the following and state what exponent law you used.
2) 36divided by 32
5) 32 divided by 36
eg. graph the equation
* substitute 0 for x and then substitute 0 for y.
Using the intercept method.
Method # 3
Slope- Intercept Form
1.) Equation must be put into y= mx + b form.
ex. graph x- 2y = 2 ( using the intercept form.)
m = 1/2 = slope
b = -1 y intercept
2.) Plot the y intercept.
3.) Use the slope rise/run to find the second point from "b".
- and when graphing it, from point "b" rise 1/2 then run 2 place.
And dont forget about the following dates:
And the next blogger is Emman.
We also continued the notes from yesterday:
m is the notation for slope: y= mx + b
If m is greater than zero, the line is diagonal and rises to the right.
If m is less than zero, the line is diagonal and falls to the right
If m is equal to zero, the line is horizontal.
If m is undefined, the line is vertical.
The larger the number, the steeper the slope, and the smaller the number, the less steep the slope is. Here is a neat video to explain slope and intercept
Our homework was Exercise 7.
Next blogger is Jhonaleen.
-Completeness (all class work and noted included, assignments completed, organized in same order as stated on the table of contents)out of 25
-Neatness(all items are neat, legible, and organized)out of 5
-And last but certainly not least the most important of all, the self reflections(I'm proud, I've improved, I still need to work on and trash it tags are included, reflections show insight into self improvement and learning)out of 10
if you need more explanation on the completed unit go to "unit one" by Xuan
oh yeah, before I forget the next person to post will be Kimberley
