The required inverse function 
= (2x - 3 ) / 4.
Given that,
f(x) = (2x+3) / 2
To find
<h3>What are functions?</h3>
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Let f(x) = y
y = (2x + 3) / 2
y * 2 = 2x + 3
2y - 3 = 2x
x = (2y - 3) / 2
Now replace y = x and x =
= (2x - 3 ) / 4
Thus, the required inverse function = (2x - 3 ) / 4.

Answer:
He should order 15 long boards
Question:
Escape park owner want 30% of each order to include long boards he wants to know how many long boards to order out of a total of 50 skateboards
Step-by-step explanation:
Let x and y represent the number of long board and the total number of skateboard to order.
Given that 30% of each order to include long boards;
x = 30% of y
x = 0.3y .....1
But, the total number of skateboard is given as 50
y = 50
From equation 1
x = 0.3y = 0.3(50)
x = 15
He should order 15 long boards
1) 210/2000=10.5%
2) What percentage of 64.99 is 45.49?
45.49/64.99=.699
.699=69.9%
This is true based on the theorem corresponding parts of congruent figures are congruent.
