Step-by-step explanation:
since you know already that it is a linear equation with a constant change rate (slope), you don't know the equation itself yet ?
you found the change rate (slope).
it is x goes up by 2, and y goes down by 6.
the slope is the ratio y/x representing the y and x changes, and it is always the factor of x.
"down" or "left" means "-","up" or "right" means "+".
the slope here is therefore
-6/2 = -3/1 = -3
so, we know the line function looks like
y = -3x + b
to get b we use one of the x y pairs like (1. 4)
4 = -3×1 + b
7 = b
and the full line function is
y = -3x + 7

Write an equation: At 2 claps, Joe is in position 7 and walking towards zero at a rate of 3 claps per minute.
Answers
Answer:
I'll assume "position 7" refers to distance and not to the order of other people.
Step-by-step explanation:
We want an equation of the form y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0). We can assume that "claps" is a new measure of distance. 0 claps is the finish.
Let's express the information provided in point format.
"At 2 claps, Joe is in position 7" is (2,7) 2 is the distance (claps) and 7 is the time (minutes)
And we can say the rate is also the slope of a line. "rate of 3 claps per minute" is 3c/m, where c is claps and m is minutes.
We can start a line equation by stating y = 3x + b, where we're using the rate, 3 c/m, as the slope, m.
We need to determine the value of b. We can use the given point (2,7) and solve for m:
y = 3x + b
7 = 3*(2) + b
b = 1
The equation becomes y = 3x + 1
y is the distance in claps and x is the time in minutes.
At a time of 2 claps he is at position of 7. b = 1 means he started 1 clap further from the finish at 0 claps.
To find the time required to reach the finish, we need to know the total distance, in claps.

Let first factorize 729

The price of a notebook has risen to $3.45 today. Yesterdays price was $3.20. find the percentage increase, round your answer to the nearest tenth of a percent.
Answers
Answer:
7.8%
Step-by-step explanation:
Yesterday’s price =$3.20
Today’s price =$3.45
Increase =today’s price - yesterday’s price
That’s $3.45 - $3.20
= $0.25
Percentage increase = increment /yesterday’s price x 100%
That’s $0.25/$3.20 x 100%

let p=0.579 compute Q
let q=0.871 compute p.
Answers
In probabilities, variables p and q are often used as complements of another.
The value of q is 0.421The value of p is 0.129The relationship between variables p and q is:
[tex]\mathbf{p+ q = 1}[/tex]
So, we have:
(a) p = 0.579
Substitute 0.579 for p in [tex]\mathbf{p+ q = 1}[/tex]
[tex]\mathbf{0.579 + q = 1}[/tex]
Make q the subject
[tex]\mathbf{q = 1 - 0.579}[/tex]
[tex]\mathbf{q = 0.421}[/tex]
The value of q is 0.421
(b) q = 0.871
Substitute 0.871 for q in [tex]\mathbf{p+ q = 1}[/tex]
[tex]\mathbf{p + 0.871 = 1}[/tex]
Make p the subject
[tex]\mathbf{p = 1 - 0.871}[/tex]
[tex]\mathbf{p = 0.129}[/tex]
The value of p is 0.129

The answer can be literally anything.
Step-by-step explanation:
The answer can be literally anything. I can see most of the answers says 3 but, that is only one of the solutions. It is the answer when questions defines the relationship as number of characters, but the question never says that. All it says is, find me a relation which satisfies few values, and then find the relationship value at a new point.
Let us start by examining the question. So here is the question in mathematical terms:
Given:
f(1)=3, f(2)=3, f(3)=5, f(4)=4 and f(5)=4
Find f(6).
So if we assume the function to be f(x) then we know its value at 5 points.
Let’s say f(6)=K, so now we know it’s value at 6 points.
Now, given the value of a function at N points, we can always find a (N-1) degree polynomial which will be that function.
Now, you can put whatever value of K you want, and you will get corresponding set of coefficient vector which will satisfy the function values at the given points.
On a side note, I don’t consider this puzzle a good puzzle, since most of the people asking it expect only 3 as answer. They basically want you to limit the way you think, in a particular direction, which I think is not a very great idea.

It concludes that 6 = 3 for the given pattern, because in "six" has "3" letters.
What is the pattern in the reasoning?A pattern is a recurring series of occurrences or elements that can be used to identify and categorize various forms of data or information.
As per the question,
1=3
2=3
3=5
4=4
5=4
If we write "1" in a word then we will write "one" and if we count the letter it will give us "3".
If we write "2" in a word then we will write "two" and if we count the letter it will give us "3".
If we write "3" in a word then we will write "three" and if we count the letter it will give us "5".
Similarly, if we write "6" in a word then we will write "six" and if we count the letter it will give us "3".
