Answer:
True
Step-by-step explanation:
Each x input has 1 y output
For this case we have the following function:

We change the variables:

From here, we clear the value of y.

Then, we make the following change:

Finally, the inverse function is:

Answer:
The inverse of the given relation is:

Answer:
18 inches wide
Step-by-step explanation:
Since the ratio of width to length is 3:7 we can assume that the length will be substancially longer than the width. The length is given as 42 inches long. To find how big the scale factor is, we divide 42 by 7 to get 6. 6 is our scale factor. take 3 x 6 =18 inches wide.
Hope this helps! :)
Answer:
tan = opposite / adjacent
Step-by-step explanation:

adjacent is 2
angle is 40
so to find the height
adjacent x tan(angle)
2(tan40)
