Answer: 
Step-by-step explanation:
We write a function f(x) which gives the values of the function that are dependent on the independent variable "x".
Given: The number of miles on the odometer can be represented by the equation y = x + 40, 000, where y is the number of miles on the odometer, and x is the number of miles you have driven it.
Here y is dependent on x, so we replace y by f(x), then we get
which is the required answer.
Y=2
if you substitute 2y in for x, you get 2y+1y=6. that is also 3y=6. 6 divided by 3 is 2 so y=2.
Answer:
<u><em>D:</em></u> Each point (or pair) in a proportional relationship must share the same difference.
Given:
Nora has a day off every 4 day while Amirah has day off every 6 days .
Nora last day off was on 29 april while Amirah was on 1 may.
To find:
When they have same day off.
Solution:
Nora last day off was on 29 april and she has a day off every 4 day.
So, her off days are
29 april, 3 may, 7 may, 11 may, 14 may, ...
Amirah last day off was on 1 may and she has day off every 6 days .
So, her off days are
1 may, 7 may, 13 may, ...
From the above two lists of off days, it is clear that they have same day off on 7 may.
