Week Three Problems
Intro: Week three was very challenging for many an(prenominal) of us. The homework took many hours to complete and there were several members with a variety of businesss. approximately of the challenges were what formula to function for the problem. Other problems ranged from knowing what sign to use and when to reduce to the lowest terms before getting the utmost correct answers.
1. 3y+9 ÷ 3y+9 = 3y+9 * y+2
5y+2 y+2 5y+2 3y+9
3y+9 * y+2 = (3y+9)(y+2)
5y+2 3y+9 (5y+2)(3y+9)
without delay use the commutative property, ab, = ba
(3y+9)(y+2) = (y+2)(3y+9)
(5y+2)(3y+9) (5y+2)(3y+9)
Now you deal simplify
(y+2)(3y+9) = y+2
(5y+2)(3y+9) 5y+2
Why do you think they were much onerous than others?
There are many formulas for each problem and they were confusing on what formula to use on what problem.
What did you do to overcome this difficulty?
I had to go to the book, homework examples, doom me how to solve this, students posts, and the facilitators examples to overcome the problems.
How did you arrive at a solution?
After several hours of reworking the problems and using all the resources unattached I could arrive at the solution.
2.
Y is directly proportional to x and that y = (-75) when x=12. Complete parts (a) and (b). equation y=kx
-75=k*12
solve for k
k= -25
4
use y=kx to find y when x =6. Replace k with
-25
4 in the equation y=kx to obtain
-25 x
4
to find y let x = 6. The following steps finish the solution
y= - 25 * (6)
4
= - 75
4 multiply.
Why do you think they were more difficult than others?
The outlook was changed from what I get down been doing which causes me anxiety and blocks my thinking. I can look at something that I have been doing and not crawfish out what steps to take or what formula to use. I have to remember this is algebra not math there is no logic, a cut and dry answers to solve. Algebra is doing...If you want to get a adequate essay, order it on our website: Orderessay
