Question

HELP

Answer 1

Which one do you need help with?

Answer 2

ALL

Answer 3

ok let's start with 26 then

Answer 4

notice we have a table of x and y values that pair up

for instance the first row has 0 under the x and 0 under the y

so when x = 0, y = 0

the second row says that when x = 2, y = 12

etc etc

Answer 5

now let's look at the answer choices

if the answer was A) y = -6x, then plugging in x = 2 *should* give you y = 12

let's see if it does

y = -6x

y = -6*2 ... plug in x = 2 (ie replace x with 2)

y = -12

so we did NOT get y = 12 like we wanted. That means choice A is NOT the answer

Answer 6

See how that works out?

Answer 7

yep.. I think that the answer is D because y=6x
12=6*2

Answer 8

right?

Answer 9

I think you meant to say B (instead of D). But yes, you are correct. The answer is y = 6x

Answer 10

wht grade r u in

Answer 11

what middle
school

Answer 12

@jim_thompson5910 Wouldn't it be y=-6x by hooke's law?

Answer 13

not according to the table Isaiah.Feynman

Answer 14

but I see how you got that negative since Hooke's Law is F = -kx

Answer 15

hello someone answer me

Answer 16

I am so confused... So is it B or y=-6x?

Answer 17

it's y = 6x

Answer 18

Okay then I got it right :)

Answer 19

for #27 couldn't I just do proportions? Would it be correct or is there another way on how to do it?

Answer 20

ANSWERRRRR ME NOW

Answer 21

you are correct

for #27, you need to solve the equation

24/30 = x/45

Answer 22

afeefa20, the question is irrelevant and way too personal. If she doesn't want to answer, then don't pressure her to do so. Besides, that sort of thing is for private chat anyway.

Answer 23

@afeefa20 Look... Why do you need that info? If I ignored your question at first.. Do you really think I would answer it? No. And also it's none of your business... I don't need a stalker..

Answer 24

@jim_thompson5910 I agree with you..

Answer 25

cuz I need to know what state u r in cuz i will help u in anything u need. If u r living in TEXAS then I would help u cuz im a highschooler who would be honored to help u in anything or anyway. SO DOES THAT ANSWER YOUR QUESTION???????????????????????????

Answer 26

Umm.. well you could have asked it differently.. Besides on my profile it does say SOFLO.. So you could have already known that I live in Florida... Okay whatever... Can you help with question #28?

Answer 27

give me a sec

Answer 28

H ?

Answer 29

8/12 = x/32

Answer 30

i would be H cuz in this problem u r doing proportions

Answer 31

for 26 rise/run so y1-y0/x1-x0 that should give the slope m for y=mx+b

Answer 32

for the slopes i think you can take any two points on each line and apply this er:
y2-y1/x2-x1

Answer 33

y=6x

Answer 34

you can even cheat by checking x and y so for instance 12 = 6(2) y=6(x)

Answer 35

eg. for the first one

(0,1) and (1,3) m= (3-1)/(1-0) = 2

Answer 36

sorry 4 the touble

Answer 37

@afeefa20 It's alright....

Answer 38

u look more older in the pic like a highschooler

Answer 39

which one r u in the pic

Answer 40

i'm on the left... and yeah i'm pretty tall

Answer 41

did you still need help blue_eyedblondie, or is it all making sense now?

Answer 42

I don't get number 33

Answer 43

and number 36

Answer 44

hmm don't see a #33 or a #36

Answer 45

it only goes up to #31

Answer 46

okay hold on

Answer 47

# 33

f(12) means "find the value of f(x) when x = 12"

so you just plug in x = 12 and evaluate

f(x) = 3x - 10

f(12) = 3(12) - 10 ... replace EVERY copy of x with 12

f(12) = 36 - 10

f(12) = 26

Answer 48

that makes sense! :)

Answer 49

for # 36, you take 30% of 1500 to get...


30% of 1500 = (30/100) * 1500 ... remember "percent" means "per hundred"

30% of 1500 = (0.30) * 1500

30% of 1500 = 450

So she must get at most 450 calories from fat

Answer 50

alrighty... I understand slopes, but the graph makes me confused for numbers 29 , 30 and 31

Answer 51

@s.mustafa88 can you explain how you got those answers?
