David was looking at his limousine bill and saw that the total number of miles he has ridden in the car was tracked:
Month
Miles
5
580
6
695
7
810
8
925
The function representing David's miles per month is f(m) = 115m + 5. What does the 115 represent?

what about this?

- Nnesha

what about the first one ?

- anonymous

2-3i?

@Nnesha @CBARREDO1 @AlexandruGuja

- Nnesha

looks right

- anonymous

what abut the one i posted as well

- CBARREDO1

115 is the rate isn't it and 5 is the number of miles at start?

- anonymous

its asking what 115 represents

- Nnesha

y =mx+b where m is slope which represent = rate of change or how things change

- anonymous

so wouldn't it be the miles at the start?

- Nnesha

y = mx + b where b is y-intercept which represent starting amount

- Nnesha

f(m) = 115m + 5 in this equation b is 5

- anonymous

im so confused tbh

- Nnesha

why?

- anonymous

nvm just skip th one i posted. i have a different on

- anonymous

What is the simplified form of the quantity 15 x y squared over x squared minus 5x plus 6 all over the quantity 5 x squared y over 2x squared minus 7x plus 3 ?

- anonymous

I am hilarious..

- anonymous

no ur not xD

- Nnesha

\[\huge\rm \frac{ \frac{ 15xy^2 }{ x^2-5x+6} }{ \frac{ 5x^2y }{ 2x^2-7x +3} }\] like this ?

- anonymous

@scenemunster You know you love my presence cx

- anonymous

yup and totally lol

- anonymous

lol

- Nnesha

first of all change division to multiplication
multiply the first fraction by reciprocal of the denominator fraction example \[\huge\rm \frac{ \frac{ a }{ b } }{ \frac{ c }{ d } } = \frac{ a }{ b } \times \frac{ d }{ c}\]

- anonymous

what goes where?

- anonymous

@Nnesha ?

- Nnesha

\[\huge\rm \frac{\color{reD}{ \frac{ 15xy^2 }{ x^2-5x+6}} }{\color{blue}{ \frac{ 5x^2y }{ 2x^2-7x +3}} }\]
red=first fraction a/b
blue= 2nd fraction c/d

- anonymous

im so confused
