Question

Y varies directly with X and has a constant rate of change of 6. When the value of Y is 11, then the value of X could be _____.


equal to zero
less than 2
equal to 6
greater than 11

Answer 1

This is direct variation, the formula is y=kx where k is the constant rate and x changes by the constant to = y.

All you have to do is sub the numbers into the equation, try it :)

Answer 2

wahts the equation?/

Answer 3

y=kx you use that for direct variation problems. Do you know what to do?

Answer 4

y=6 ???

Answer 5

oh nvm y=11

Answer 6

Yes y=11 the question says that.

Answer 7

So 6=kx what would you do now?

Answer 8

find x

Answer 9

Your given k right?

Answer 10

no

Answer 11

k = constant rate of change

Answer 12

so six

Answer 13

Yes

Answer 14

Can you solve x now?

Answer 15

is the equation 6=6x

Answer 16

y = 11 not 6 remember in the question?

Answer 17

so 6=11x

Answer 18

No y = 11, and k= 6.
11=6x.

Answer 19

un ok 11=6x how culd x equal anyof those im not understanding

Answer 20

The rate of change or k, multiplied by x will equal to y. k is just gradient or m,know that right?
