Question

will medal and fan!!!!

Raven’s parents bought a 20’ ski boat for $22,000. After 2 years, the boat was worth 17,500. Using x as the number of years and y as the boat value, graph the two points.

Part 1: [2 points] Describe the slope of the line which connects the two points.

Part 2: [3 points] How can your graph be used to predict the value of the boat in 5 years?

Part 3: [2 points] What is the projected boat value in 5 years?

Answer 2

can u explaian to me this cuz i know this a lot

Answer 3

*explain hoe to this

Answer 4

"Hoe" xD

Yeah, I get what you mean, sure.

Answer 5

lol oops *how

Answer 6

xDDDD omg lol

Answer 7

(0, 22,000) and (2, 17,500)

M = (y2 - y1) / (x2 - x1)

\(\ M = \dfrac{ 17,500 - 22,000}{2 - 0} \implies \dfrac{-4,500}{2} \implies -2,250 \)

y - y1 = m(x - x1)

y - 22,000 = -2,250(x - 0)

y - 22,000 = -2,250x
+22,000 + 22,000

y = -2,250x + 22,000

Once you plot that, it'll be your function. y = f(x) so; f(5) = -2,250(5) + 22,000 --> -11,250 + 22,000 = 10,750

After 5 years, the boat will be worth $10,750

Answer 8

0,o whoah THANK YOU SOOOOOOO MUCH lol *Hoe* do u know all this???

Answer 9

lol

Answer 10

Oh, I studied this a long time ago ~

You can graph it, just enter "y = -2,250x + 22,000" into Desmos

Answer 11

lol cool well thank u sooooo much really appreciated

Answer 12

For part B, it's asking for when you look at your graph, look for the x interval 5, and see what y interval corresponds to it. ^_^

Or you can use a function to make it easier
