Question

Suppose x and y vary together such that y = 4 x 11 .
suppose x varies from x = 2 to x = 7.5 .
over this interval, by how much does x change?

Answer 1

Answer:

To find the change in x over the given interval, subtract the initial value of x from the final value of x.

Initial value of x = 2

Final value of x = 7.5

Change in x = Final value of x - Initial value of x

Change in x = 7.5 - 2

Change in x = 5.5

Therefore, over the interval from x = 2 to x = 7.5, x changes by 5.5.
