## anonymous one year ago Which of the following expressions is the conjugate of a complex number with 2 as the real part and 3i as the imaginary part? 2 + 3i 2 − 3i 3i + 2 3i − 2

1. Nnesha

you just need to change the sign of imaginary number

Don't do it

5. Nnesha

what?

6. CBARREDO1

Don't click the link, he thinks he is funny 7-7

7. CBARREDO1

3i+2

8. anonymous

lol lameeeee but seriously i need help XD

9. anonymous

and ive been asking if it's 3i+2 and you are the only one who answered back. so that's the answer??

10. anonymous

it's 2-3i

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 the first one ?

15. anonymous

2-3i?

@Nnesha @CBARREDO1 @AlexandruGuja

17. Nnesha

looks right

18. anonymous

what abut the one i posted as well

19. CBARREDO1

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

20. anonymous

21. Nnesha

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

22. anonymous

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

23. Nnesha

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

24. Nnesha

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

25. anonymous

im so confused tbh

26. Nnesha

why?

27. anonymous

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

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 ?

29. anonymous

I am hilarious..

30. anonymous

no ur not xD

31. Nnesha

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

32. anonymous

@scenemunster You know you love my presence cx

33. anonymous

yup and totally lol

34. anonymous

lol

35. Nnesha

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

36. anonymous

what goes where?

37. anonymous

@Nnesha ?

38. 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

39. anonymous

im so confused
