A. neither
B. inverse variation; y = 20/x
C. direct variation; y = 20x
D. direct variation; y = x+15

Answer 9

hold on

Answer 10

@misty1212 and ok

Answer 11

HI!!

Answer 12

hi can someone help me?

Answer 13

which one are you doing?

Answer 14

both. preferably the first one first then the second one @misty1212

Answer 15

as x gets bigger, then y gets smaller right?

Answer 16

yep

Answer 17

lets check if it is \[y=20x\]
is \[20=10\times 5\]?

Answer 18

er....... sorry my brain is kind of fried normally i'd be able to do this quickly

Answer 19

take your time,\(10\times 5\) is not that hard to do

Answer 20

oh! right! sorry. hehe. dumb moment. 50

Answer 21

ok so we can forget that one

Answer 22

\[y=x+15\] is not direct variation so we can forget that one too

Answer 23

so it's either a or b?

Answer 24

and \[y=\frac{20}{x}\]means if you divide \(20\) by \(x\) you should get \(y\)

Answer 25

if \(x=20\) then \(y=5\) from the table
is
\[5=\frac{20}{20}\]?

Answer 26

20/20 is 1 so would it be b?

Answer 27

?

Answer 28

no not B since as you said \(\frac{20}{20}=1\) not \(5\)

Answer 29

oh right! sorry. ugh....... I hate math. thanks again.

Answer 30

yw

Answer 31

can you help me with the second one too if i'm not too much of a pain?

Answer 32

gotta do it quick
\[y=\frac{k}{x}\] or
\[xy=k\] you have \(y=30,x=44\) so
\[k=30\times 44=1320\]

Answer 33

put \(x=55\) and compute \[y=\frac{1320}{55}\] to get your answer
good luckn !

Answer 34

ty!
