Step-by-step explanation:
In order to get the inverse of equation, we will interchange the variables and solve for x and y as follows.

whereas, 
or x = 
Now, on interchanging the variable we will get the equation as follows.


y = 
Answer:
The length of the diagonal is 11.879 units
Step-by-step explanation:
On any rectangle or square, any 2 adjacent sides and the diagonal that connects them makes a right triangle. The diagonal is the hypotenuse of that right triangle, and you can find it using the pythagorean theorem:

where a and b are the sides, and c is the diagonal.

Answer:
24 pictures for $5
Step-by-step explanation:
To find out the better value, we have to find the price of a singular picture. To do this, we will divide each number by the amount of pictures.
For the first deal, 36 pictures cost $8, so 1 picture costs about $0.22.
For the second deal, 24 pictures cost $5, so 1 picture costs about $0.21.
Since the second deal costs less, it is a better deal.
