Answer:
x + 3 / 2 = y
Step-by-step explanation:
to change a function to its inverse we need to do three basic things
1. change f(x) to y
so for the example i gave which is f(x) = 2x - 3; this will now be
y = 2x - 3
2. we need to switch the position of the x's and y's, that means x becomes y and y becomes x
x = 2y - 3
3. finally we make y the subject of the formula
x + 3/ 2 = y, this new expression for y is the inverse of the function and can be written as
f^-1(x) = x + 3/2

Answer:
(b) 7720 mm² of paper
Step-by-step explanation:
The central horizontal rectangle of the net is 80 mm high and ...
40 + 5.5 + 40 + 5.5 = 91
mm long. Its area 9 is ...
(80 mm)(91 mm) = 7280 mm²
__
The two pieces of the net not accounted for above are the "flaps" above and below the central rectangle. Each of those two has an area of 40 mm by 5.5 mm, so their total area is ...
2(40 mm)(5.5 mm) = 440 mm²
Then the area of paper needed for the wrapper is ...
total area = 7280 mm² + 440 mm²
total area = 7720 mm²
