Question

Find the constant of variation for the relationship f(x)= 40x.

A.
f(x)

B.
x

C.
20

D.
40

Answer 1

f(x) = 40x means that the constant of variation is 40

Answer 2

ok. thanks What about this one?

Answer 3

A.
2

B.
3

C.
4

D.
1

Answer 4

table says
x|1|2|3|4
y|3|6|9|12|

Answer 5

Okay here is how you find this hun.

Look at the top line, "X" it is going
"1, 2, 3, 4"

So how much is it going by to get the next number?

Answer 6

@noneyabusiness ? you there?

Answer 7

yeah

Answer 8

+1?

Answer 9

That's right! So x has a constant of +1

now what about Y ?

Answer 10

+3

Answer 11

Yup! So that means that for every x (1), you add 3 to y. So if the next number on the line x was 5, y would be 15. See how it works?

Answer 12

Is the constant 3?

Answer 13

Yes. Y has a constant of +3

Answer 14

so answer B

Answer 15

yay! you are really smart!

Answer 16

Thank you :D

Answer 17

you are welcome

Answer 18

Any more you nee help with?

Answer 19

yes please

Answer 20

If f(x) varies directly with x, and f(x) = 10 when x = 4, write the direct linear variation equation.

A.
f(x)=10x

B.
f(x=4x

C.
f(x)=5/2x

D.
f(x)=2/5x

Is it b?

Answer 21

Okay, let me figure it out, I will post the answer in just a sec

Answer 22

ok

Answer 23

Okay, it is C,

f(x)= 5/2x

Answer 24

i see how you did it too

Answer 25

Okay cool, You need help with any more?

Answer 26

nope! thanks though

Answer 27

You are absolutely welcome!
