Help represent and accuracy with work sample

Answer 1

in any way, can you HELP me represent what i need to do to solve this in graph form, etc

Answer 2

Answer 3

"use models, pictures, diagrams and/ or symbols to represent and solve the task situation and select an effective strategy to solve the task"

Answer 4

It would be really nice if someone could help me through this

Answer 5

You would graph this in slope intercept form. Why? You are given a height at the start of the experiment, and want to see the growth each day (it increases at a constant 3 inches a day).

So we write the equation in the following format:

\(\large\bf{y=mx+b}\)

\(\bf{b=y-intercept}\)
\(\bf{m=slope}\)

`Variety A was 12 inches tall when planted`

This is the start, or 0. So your point is `(0,10)` this is your y-intercept.

`...and grow 6 inches per day`.

It increases by 6 units each day, this is your rate.

How would you write this in `y=mx+b` format?

Answer 6

Hmmm, y = 12x + 6 ?

Answer 7

mm not quite.

Remember above i stated that `12 inches` was the given height on day 0. So this means that `12` is your `y-intercept` so it is `b` in `y=mx+b`. This means that `6` is `m` because it is the rate it is growing at `(being 6 inches each day)`.

So your equation will be written as: \(\bf{y=6x+12}\)

U understand?

Answer 8

Ohhh... ok ok ya i see

Answer 9

Okie nice cx

So how would you write `Variety B was planted the same day (remember day 0), was 30 inches tall and grows 3 inches each day` in `y=mx+b`?

Answer 10

y = 3x + 30

Answer 11

Nice!

Answer 12

Answer 13

Now we have this algebraic already.

Now we graph it.

To graph this we first plot the y-intercept onto a graph, and then apply the rate. (you can use desmos.com if you'd like)

Answer 14

Ok one sec (:

Answer 15

okie nice cx We want to apply both equation to see what day they will meet.

Answer 16

(6,48)

Answer 17

Yes. So the day they both have the same height is the 6th day with the same height of 48 inches cx

Answer 18

ahh thanks so much.... u really helped me ((:

Answer 19

No problem XD
