Answer 12

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?

Answer 13

what about this?

Answer 14

what about the first one ?

Answer 15

2-3i?

Answer 17

looks right

Answer 18

what abut the one i posted as well

Answer 19

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

Answer 20

its asking what 115 represents

Answer 21

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

Answer 22

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

Answer 23

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

Answer 24

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

Answer 25

im so confused tbh

Answer 26

why?

Answer 27

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

Answer 28

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 ?

Answer 29

I am hilarious..

Answer 30

no ur not xD

Answer 31

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

Answer 32

@scenemunster You know you love my presence cx

Answer 33

yup and totally lol

Answer 34

lol

Answer 35

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

Answer 36

what goes where?

Answer 37

@Nnesha ?

Answer 38

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

Answer 39

im so confused
