@Nnesha please tell me if this is correct or am i off track?

3. Here_to_Help15

4. Here_to_Help15

My response vv

5. Nnesha

looks correct bec we have to multiply x and y value by 4 to get new coordinates

6. Here_to_Help15

So im all good ?? :D

7. Nnesha

8. Here_to_Help15

24. Here_to_Help15

@sourwing can you help?

25. Here_to_Help15

@freckles can you help?

26. Here_to_Help15

@Ashleyisakitty ?

27. Here_to_Help15

I just need to know if ^ is correct :/

28. freckles

if the scale is a units =b other units then in the picture it says x units you multiply both sides by a/x and you have x units=ba/x other units

29. Here_to_Help15

So 39 feet correct?

30. Here_to_Help15

39 ft *

31. freckles

sounds great since 1cm=10ft and multiplying both sides by the scaler number 3.9 we have 3.9 cm=3.9*10 ft

32. Here_to_Help15

Ok thankss and please tell me you can help me with a couple more?

33. freckles

sure

34. Here_to_Help15

35. Here_to_Help15

@freckles

36. freckles

ok you actually have 3 right triangles in the picture and some similar triangle action |dw:1434334984001:dw| let's try to find h

37. freckles

|dw:1434335103474:dw| maybe try to use the right triangle fact to solve for h

38. freckles

actually doing that way you might be able to find the part b first (depending on how you solve)

39. Here_to_Help15

Woah woah

40. freckles

then from that you can find your part a

41. freckles

are you there?

42. Here_to_Help15

Yes im so sorry im multitasking

43. freckles

Ok have you solved the system above?

44. Here_to_Help15

Sorry i am not understanding this and trust me its not you its my brain, i cant comprehend these specific questions

45. freckles

did you see all the right triangles in your picture?

46. freckles

you had 3 right triangles

47. Here_to_Help15

Yes

48. freckles

that is where the 3 equations came from Pythagorean theorem is what was used to get those equations

49. freckles

|dw:1434336032289:dw| these things I circled are both equal to h if I set them equal to each other then I have two equations in terms of l^2 and m^2 and you can use elimination to solve the system for either m^2 or l^2 you might prefer to solve for m^2 by elimination the l^2 since m is the length you want to find in b

50. freckles

$\sqrt{l^2-4^2}=\sqrt{m^2-18^2} \\ \text{ \square both sides } \\ l^2 -4^2=m^2-18^2 \\ \text{ subtract } l^2 \text{ on both sides } \\ \text{ add } 18^2 \text{ on both sides } \\ 18^2-4^2=m^2-l^2 \\ 22^2=m^2+l^2 \text{ is the other equation }$ do you see how this is setup for elimination on the l^2 thingy you can add the equations and then solve for m

51. Here_to_Help15

yes you are a little clearer,but if you dont mind im just gonna guess @freckles but thank you so much ! :)

52. freckles

well I guess I'm not clear enough if you just want to guess

53. freckles

pretend i have a+b=c and a-b=d if I add the equations I have 2a=c+d (the b got eliminated since +b-b=0)

54. freckles

55. Here_to_Help15

@freckles you are doing everything right its me who doesn't

56. Nnesha

it's okay if you get it wrong like you said it's prep PRACTICE EXAM exam/test/quiz aren't allowed

57. Here_to_Help15

Yea yea sure but i dont want my teacher to see a humiliating practice score :/
