Question

please help! :)

Answer 1

What with :)

Answer 2

Hmmmm.....

Answer 3

hint: what is the slope of the graph?

Answer 4

10

Answer 5

nope

Answer 6

use the point slope formula

Answer 7

pick two points on the graph

(0,0) and (2,9) = (x1,y1) and (x2,y2)

then find m = slope = (y2-y1)/(x2-x1) = ?

Answer 8

@Vocaloid

Answer 9

y(y−1)/(x−1)

Answer 10

nope, read carefully.

Answer 11

y(y−1)/ x(x−1)

Answer 12

x1 = 0
y1 = 0

x2 = 2
y2 = 9

slope = (y2-y1)/(x2-x1) = ?

Answer 13

i dont know how to do that

Answer 14

what is the slope ?

Answer 15

90 / 20

Answer 16

almost.

Answer 17

y2 = 9
y1 = 0

y2-y1 = ?

Answer 18

9 / 2

Answer 19

good, now convert to decimal

Answer 20

4.5

Answer 21

good now

p = (slope)(s)

Answer 22

and pick the answer that matches

Answer 23

b

Answer 24

good

Answer 25

@Vocaloid

Answer 26

old length = 8
new length = 5.5*old length = ?

Answer 27

44

Answer 28

good

old width = 6
find the new width

Answer 29

264

Answer 30

no

Answer 31

remember, a scale factor of 5.5 means we multiply each dimension by 5.5

Answer 32

how do i find the nwe width

Answer 33

multiply the old width by the scale factor.....

Answer 34

follow the same pattern we used to find the length

Answer 35

242

Answer 36

no.

Answer 37

new width = scale factor*old width

Answer 38

33 @Vocaloid

Answer 39

good

so we have length = 44
and width = 33

now find the perimeter and area.

Answer 40

how ?

Answer 41

please memorize these two equations.

perimeter = 2(length+width)
area = length*width

Answer 42

ok

Answer 43

now find the perimeter and area....

Answer 44

27?

Answer 45

no...

Answer 46

perimeter = 2(length+width) = ?

Answer 47

2 ( 8 + 5.5 )

Answer 48

no...

Answer 49

remember we just calculated length and width...

Answer 50

length = ?
width = ?

please look back at what we wrote earlier.

Answer 51

8 and 5.5

Answer 52

nope.

Answer 53

go back.

Answer 54

read through everything we have written so far.

Answer 55

8 and 44

Answer 56

nope.

Answer 57

read carefully.

Answer 58

im so confused

Answer 59

I already told you what the length and width were. what are they?

Answer 60

start from the beginning and read carefully.

Answer 61

8 and 5.5

Answer 62

nope.

Answer 63

pay attention.

length = ?

Answer 64

but thats what you said it was

Answer 65

nope.

Answer 66

6

Answer 67

look at the attachment.

Answer 68

now tell me what the length and width are.

Answer 69

44 and 33

Answer 70

good. now find the perimeter and area.

Answer 71

what do i calculate to find the perimeter?

Answer 72

use the equations I just gave you.

Answer 73

154

Answer 74

good now find area.

Answer 75

how?

Answer 76

use.
the.
equation.
