Linear Functions and Equations

13. 2x+y=6 plot-ordered pair as a point in a number plane.

y= 6-2x horizontal axis-horizontal number line

14. 5x+y=7 origin-point of intersection at y & x on a coordinate

y=7-5x vertical axis-second number line

15. 3x+2y=8 x-axis-horizontal axis

y=-3/2x+4 y-axis-vertical axis

16.2x+5y=10 graph of ordered pair-(2,3)

y=-2/5x+2 coordinates- shown as pair of letters/numbers (2,3)

x-coordinate- position of coordinate according to x-axis

y-coordinate-position of coordinate according to y-axis

coordinate axes- y/x axes

coordinate plane- contains 2 perpendicular axes(x,y)

quadrants- quarter of a circle or its circumference

linear equation-relating to a line, straight direction

Graph of Equation-2 variables that consist of all points that are the
solution to equation.

Monthly Income

I want to be a famous Cosmetologist. I get $1200 a month.

1) Your rent plus utilities (gas, water, internet, phone, etc.) is $540 a month! What percentage of your monthly income is this?

My utilities would be about 45% of my monthly income.

2) You spend about 6% of your income per month on your cell phone bill! What amount is this?

My cell phone bill would be about $72.00 out of my monthly income.

3) You usually spend around $200 per month on groceries. Find this percentage.

Grocerys would cost about 17% or 16.66666% of my monthly income.

4) You spend about $40 per week on gas filling your car's gas tank! What percentage of your monthly income is spent on gas?

3.33333% would be spent on gas.

5) You like to use the remaining money and split it - using 60% on entertainment (movies, shopping, etc.) and putting the other 40% in savings. About how much money is spent on entertainment and how much is put in savings?

The final price after all of my bills in one month would be $214.67. So with entertainment, would spend about $128.80. I would have $84.87 left to put into savings.

Polynomial Post

The Unlike terms are so much clearer to me now! I never really understood how I would do a problem like 4y+3x=68, but now that is so much more clear to me!!

I honestly never knew how much we use polynomials! I can't believe that we used them from Kindergarten, all the way through High School! I think that is amazing. I also never really understood what a coefficient was, but now I understand what the coefficient is.

Gas Prices

With these new gas prices, I would be paying $35.20 to fill my gas tank! This is a $16.80 difference from the $52 it would have costed a month ago!! This is amazing!

The lowest gas price I have seen is $1.56 at Marathon on Center St.!!

I have read this article and have learned very much interesting information on why the gas prices are dropping. First I learned that the gas price has been declining for 56 days straight. The price has been declining since hurricane Gustav and Ike tore up the Gulf Coast in September. I also learned that the record high on July 17 was $4.114, however the gas prices have dropped 46.5% since then. This information is absolutely amazing.

Assignment 5

I chose the article 30 days 30 ways to save: clothing repair. I chose this article because I really like shopping for clothes, this title had the word clothes in it so I chose this article. From this article I learned that clothing stores are seeing a dip in business while alteration stores are not. You should examine clothes thoroughly, if it is not worn, or damaged and is in good shape then you should just give it a new style. This was a very good article.

How Much I Pay a Week on Gas

My car is definitly not good on gas! If I had a pontiac g6 convertible, I would be paying $52 a week! My cars tank holds 16 gallons and gets 26 miles a gallon. If I were driving 350 miles a week, I would pay $52 a week.

I'm not really sure about this but what I tried to set up how much I would pay a month, I took the amount I would pay a week, and multiplied that by 4, because there is 4 weeks in a month.
I think that I would pay about $208 on gas a month. I don't know how I got this answer.

My Dream Car

If I could get any car that I wanted I would get a black, Pontiac g6 convertible. I would buy this beautiful car because it is a great car, and the black just makes it so much better! This car is also pretty good on gas, and like I said, it is just so beautiful! This cars gas tank will hold 16 gallons, and you get 26 miles per gallon when driving. But you better have a good first job because it costs, $3.25 per gallon, so to fill this car up, it would cost $52! But I'm sure that I would have a very good job and be a successful girl, with a great car!!
