Question

can anyone help me with solving this application the yearly production of a 6 foot orange tree is 38 lbs and a 12 foot tree producing 84 lbs of oranges?

Answer 1

Ah ok.

Answer 2

So, what exactly is the question? It's just making a statement. Are we supposed to say how many pounds of fruit were created?

Answer 3

no your given the numbers for each lbs of oranges two pairs what be (6,38) and (12,84)

Answer 4

h represents height of a tree and p represents lbs of oranges

Answer 5

this is the formula p-38=23/3(h-6)?

Answer 6

Ah, ok! Let's see...

Answer 7

Let's get slope first.
y1-y2 / x1-x2

(6,38) and (12,84)

So,
38-84 = -46
6-12 = -6
-23/-3
23/3

Liking your slope so far.

Answer 8

y-y1 = m(x-x1)
y-38 = 23/3(x-6)

Yup! Now, we just need to simplify some more.

Answer 9

were using p-p1=m(h-h1)

Answer 10

y - 38 = (23/3)x - 6(23/3)
y - 38 = (23/3)x - 138/3
y = 23/3x - 138/3 + 38
Now we have to try to combine the 38 with the -138/3.

You tell me what we do here.

Answer 11

substitute the values p1 and h1

Answer 12

True. I was using the generic form of it. But we can go ahead and change the letters to specifics:
p = 23/3h - 138/3 + 38

Now how do we add 138/3 and 38 together to make one fraction?

Answer 13

p-38=23/3(h-6) are u familiar with this equation?

Answer 14

Yup. I did say you were correct there. But recall what I said earlier:
y - 38 = (23/3)x - 6(23/3)
y - 38 = (23/3)x - 138/3
y = 23/3x - 138/3 + 38
Now we have to try to combine the 38 with the -138/3. You tell me what we do here.

Answer 15

If you'd like, I'll go ahead and swap out the letters for you:
p - 38 = (23/3)h - 6(23/3)
p - 38 = (23/3)h - 138/3
p = 23/3h - 138/3 + 38
Now we have to try to combine the 38 with the -138/3. You tell me what we do here.

Answer 16

the trouble im having is coming up with finding the numbers unknown for a certain lb of oranges for example 18 foot tree, 20 foot tree etc

Answer 17

are we subtracting the 2 numbers ?

Answer 18

are u there uber1337h

Answer 19

Oh sorry, I was on facebook. lol.
What you want to do is get a common divisor. We have -138/3 and 38. 38 as a fraction is 38/1, right?

Answer 20

also u left off the h near the fraction

Answer 21

always keep your variable near that fraction

Answer 22

that last post was after you do the equation

Answer 23

which one?

Answer 24

that is the step after you set up your equation

Answer 25

-138/3+ 38/1?

Answer 26

p - 38 = (23/3)h - 6(23/3)
p - 38 = (23/3)h - 138/3
p = 23/3h - 138/3 + 38

I don't see any missing H's :(

Answer 27

-138/3h+38/1 oops

Answer 28

Ah that. There is no h, though. That's why I was telling you we have to combine them.

Answer 29

where did it go

Answer 30

There never was one there to begin with. I'll show you the steps one at a time.

Answer 31

it has to stay in the equation according to mymathlab

Answer 32

p-38=23/3(h-6)

We started here.

Answer 33

Now, distribute the 23/3 to (h-6)

We'd have (23/3 times h) - (23/3 times -6)

Answer 34

Does that make sense so far?

Answer 35

but we use the fraction in the equation which the h is representing the height of the orange trees so we have use the h

Answer 36

And we do still use h. What do you get when you do this:

"Now, distribute the 23/3 to (h-6)
We'd have (23/3 times h) - (23/3 times -6) "

Answer 37

let me show the equation in my math lab it says p-38=23/3h -46 was one of the answers to express p in terms of h remove parenthese

Answer 38

And we will. Just do the equation I asked you to. :P

Answer 39

does this make sense to you then u have to add 38 and simplify

Answer 40

im not sure what you want me to do?

Answer 41

Yup. That's what I've been asking you to do.

Answer 42

oh -138/3?

Answer 43

Yup. -138/3 plus 38.

Answer 44

I've gotta go soon, so I'll tell you what we do:

Answer 45

Since we know that 38 = 38/1 in fraction form, we multiply by 3/3 and get:
(3(38))/1(3)

Answer 46

im not sure how the got the 46? lol

Answer 47

Hmm... 46 can't be right, as far as I can tell. lol

Answer 48

ok but how do they get the 46 in the equation?

Answer 49

Like I said, I think they made a typo. :(

Answer 50

that was the first equation they did in the mathlab

Answer 51

they were trying to find the number f lbs for a 18 foot tree and 20 foot tree

Answer 52

p - 38 = (23/3)h - 6(23/3)
p - 38 = (23/3)h - 138/3
p = 23/3h - 138/3 + 38

So now we have this:
p = 23/3h - 138/3 + 414/3

By adding the 414/3 and -138/3, we have: 276/3

Answer 53

well its no typo its in my study plan module i plug in the wrong answer and they gave their answer

Answer 54

there is about 4 parts to this word problem application

Answer 55

remember its a word problem u are find number of lbs per 18 foot tree and and 20 foot tree here

Answer 56

were using the same equation in the first half to answer these problems

Answer 57

Alright, so let's do this one step at a time. I see what the problem is.

Answer 58

Remember this equation? p-38=23/3(h-6)

Answer 59

yes

Answer 60

Awesome. First of all, let me double check. Did you get that by yourself? And if not, are you sure you know how we got to that equation from just the two points that were given to us?

Answer 61

Still here? Gotta go soon.

Answer 62

Lemme know if you still want to do this. I need to head to bed soon.

Answer 63

hello u there

Answer 64

yes im in my study plan online in classroon portal

Answer 65

Sigh... I guess since you at least tried a little, I'll tell you what it is...

p = (23/3)h - 8

I wanted to explain it more in depth, but you kinda left abruptly. Just hit me up some other day and I'll try to explain it more in depth. But basically, this should explain it:

p - 38 = (23/3)h - 6(23/3)
p - 38 = (23/3)h - 138/3
p = (23/3)h - 138/3 + 38
p = (23/3h) - 46 + 38
p = (23/3)h - 8

Anyhow, the reason I thought -46 was a typo is because I didn't realize that -138/3 = -46. Remember to ask me in the future for more information if you see me.

Answer 66

Ah, good to see you're back then. :P

How do you like that answer?

Answer 67

the computer will plug in the answers when u give the wrong answers but some steps are skipped

Answer 68

The -46 came from the -138/3 that we got earlier. So just use this work and it should be all happy.

Answer 69

im here waiting

Answer 70

For what?
