I have a problem where I need to figure out how many pounds of fruit an 18 ft & a 20 tree will bear. Here is the formula: p-24=31/11(h-5). For the life of me I am stuck and can't figure it out. Please help and show me.

    do you not just plug in 18 for the height and solve for p?

    is the formula p-24 = 31/(11(h-5))

    I used the formula I just put and got 24.94 pounds for the 18 ft tree and 24.56 pounds for the 20 ft tree.

    no Here is the ordered pair (5,24) & (16,55) then I did 55-24/16-5 = 31/11

    the equation came to p-24=31/11(h-5)

    I am suppose to take that equation and predict the # of lbs of fruit a 18 & a 20 ft tree will produce

    dang. I left the page and when I went back the problem was gone so now I will have to do a different one. Sorry I will have to post a different problem.

    oh you are trying to find the equation of the line? y = mx +b m = (55-24)/(16-5) = 31/11 y = 31/11(x - 5) + 24 for x=18 y = (31/11)*3+24 = 32.45 for x = 20 y = (31/11)*5+24 = 38.09

    you line equation was incorrect. Use point-slope form. \[y = m(x -x _{1})+ y_{1}\]

    that is not the formula they are using. They are using m= p2-p1/h2-h1=

    I can rearrange yours to do the same thing: p2 - p1 = m(h2-h1) p2 = m(h2-h1) + p1

    ok the new formula, since I had to change problems, is p-18=20/3(h-6)

    p1 & p2 = 18 & 58 and h1 & h2 = 6 & 12 respectively

    ok so p = (20/3)*(18-6) + 18 p = (20/3)*12 + 18 = 98

    132 was wrong. Remember we said the answer was 98. 132 was the answer you got when you didn't do the () first

    334/3 is the right answer for the height of 20

    but it says to round it to the nearest whole nmuber

    334/3 = 111.33 which is approximated to 111 when rounding to the nearest whole number

    ok last thing. i need to predict the height of a tree that produces 88 lbs. can you tell me how to flip the formula around to solve for that?

  46. anonymous

    so the formula we were using was: p = (20/3)*(h-6) + 18 subtract 18 from each side p-18 = (20/3)*(h-6) divide each side by (20/3) this is the same as multiplying by 3/20 (3/20)*(p-18) = h-6 now add 6 to each side our new equation is h = (3/20)*(p-18) + 6
