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 abut the one i posted as well

115 is the rate isn't it and 5 is the number of miles at start?
anonymous
  • anonymous
its asking what 115 represents
Nnesha
  • Nnesha
y =mx+b where m is slope which represent = rate of change or how things change
anonymous
  • anonymous
so wouldn't it be the miles at the start?
Nnesha
  • Nnesha
y = mx + b where b is y-intercept which represent starting amount
Nnesha
  • Nnesha
f(m) = 115m + 5 in this equation b is 5

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

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

what goes where?

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