If y varies directly with x, Write an equation relating x and y when y = -30 and x = 6.
ziro4ka [17]

Answer:

y=-5x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

so

For x=6,y=-30

substitute

y/x=k------> k=-30/6=-5

therefore

y=-5x

From the question, we are told that Bobbie has 100 more followers than Debora and x is used to represent the number of followers that Debora has.

Describe a way to check the correctness of a subtraction answer.
Tamiku [17]

Step-by-step explanation:

Well in general, we can represent subtraction as: x-y=z

"z" represents the difference, and it really just represents x with y taken away. So if we were to "give back" this y value, we should get "x".

This means that: z+y=x

So one way to check, is adding the value that's being subtracted (y value) and the difference (z value), this should get you the value that is being subtracted from (x value). If you don't get the original value that's being subtracted from (x-value) then you know the answer you got is wrong.
