Will medal + fan!!!


What is the rate of change?
–2x + 4y > 8

Answer 1

make it a function of y respect to x

Answer 2

x=time and y=the volume or substance

Answer 3

What? @raffle_snaffle

Answer 4

Isolate y.

Answer 5

how do I isolate y @swagmaster47?

Answer 6

The same way you would do it if it was –2x + 4y = 8

Answer 7

Just subtract 2x and divide the quantity by 4

Answer 8

like you would any function with an equals sign just remember when you are dividing by negative you have to flip the < sign

Answer 9

You actually don't need to worry about that in this problem, since it would have no effect on the rate of change. @raffle_snaffle

Answer 10

what do I subtract -2x from?

Answer 11

both sides

Answer 12

so I end up with 4y then dividing 4 by 4y isolates y right?

Answer 13

or wait no i get 2y or no

Answer 14

isolate y...

Answer 15

you have a question swagmaster?

Answer 16

-2x + 4y = 8
+ 2x +2x
4y = 2x + 8
then divide both sides by 4

Answer 17

I divide 4y and 2x + 8 by 4 @swagmaster47?

Answer 18

Yes so
y = (1/2)x + 2

Answer 19

And the rate of change is the slope which is 1/2

Answer 20

thanks @swagmaster47
