Question

Help Please! I will give a medal! Please Help!

Answer 1

Write a translation rule that maps point D(7, -3) onto point D'(2, 5).

Answer 2

@MathLegend

Answer 3

One sec

Answer 4

OK, thnks

Answer 5

Do you know how to find the slope?

Answer 6

No...

Answer 7

D(7, -3) onto point D'(2, 5)

Lets subtract D' - D

X-values... 2-7 = ?
Y-values... 5-(-3) = ?

Answer 8

@Pretty_Princesses what do your x and y values equal?

Answer 9

Ok......

2-7 =5
5-(-3) = 8

Answer 10

x-value = -5
y-value = 8

Answer 11

oops forgot the - sign.

Answer 12

To write that... we simply do this...

(x-5, y+8)

Answer 13

Do I solve it^^^^^?

Answer 14

Oh, no I did it backwards!

Answer 15

oh ok

Answer 16

x-values... 7-2 = 5
y-values... -3-5 = -8

Right?

Answer 17

(x+5, y-8)

Answer 18

The reason I knew I did it backwards was by plotting the point and following the rule.

Answer 19

Right.

Answer 20

Make sense?

Answer 21

That is your rule.

Answer 22

Yes it does.

Answer 23

I get it.

Answer 24

I have a other problem is that OK? @MathLegend

Answer 25

Which of the images above represents a poof of the Pythagorean Theorem? Explain your choice, and then explain how the figure proves the Pythagorean Theorem.

Answer 26

Do notice the each leg of the triangle? I want you take picture 1... and add up the legs and tell me if they equal the hypotenuse... then do the same for the 2nd picture. Tell me which one equals the hypotenuse.

Answer 27

ok please wait....

Answer 28

will do :)

Answer 29

For the 1st one do I add the numbers like 64^2 + 36^2 + 9^2 = 5, 473 ? ? ?

Answer 30

No, the numbers they give you are already squared. So simply add them.

Answer 31

oh oh oh .... I'm lost !

Answer 32

Lets take the 1st picture...

Answer 33

Ok.

Answer 34

Leg 1 = 9
Leg 2 = 36
Hypotenuse = 64

Does...

9 + 36 = 64 ?

Answer 35

mmmm.... no

Answer 36

No. it = 45

Answer 37

Okay, so that is not Pythagorean theorem.

Answer 38

What about the other one...

Leg 1 = 25
Leg 2 = 144
Hypotenuse = 169

25 + 144 = 169

Does that work out good?

Answer 39

Yes. it does

Answer 40

So that means it follow Pythagorean theorem....

Answer 41

yes

Answer 42

It shows you that

\[a ^{2}+b ^{2}=c ^{2}\]

Answer 43

The original of ...

25 + 144 = 169

is

\[5^{2}+12^{2}=13^{2}\]

If you took the square root of the first set of numbers.

Answer 44

Understand @Pretty_Princesses ?

Answer 45

ok I understand. :)

Answer 46

Yes I do

Answer 47

thnx again

Answer 48

No problem
