Since f(g(x)) = g(f(x)) = x, hence the function f(x) and g(x) are inverses of each other.
<h3>Inverse of functions</h3>
In order to determine if the function f(x) and g(x) are inverses of each other, the composite function f(g(x)) = g(f(x))
Given the function
f(x)= 5-3x/2 and
g(x)= 5-2x/3
f(g(x)) = f(5-2x/3)
Substitute
f(g(x)) = 5-3(5-2x)/3)/2
f(g(x)) = (5-5+2x)/2
f(g(x)) = 2x/2
f(g(x)) = x
Similarly
g(f(x)) = 5-2(5-3x/2)/3
g(f(x)) = 5-5+3x/3
g(f(x)) = 3x/3
g(f(x)) =x
Since f(g(x)) = g(f(x)) = x, hence the function f(x) and g(x) are inverses of each other.

Bottom left corner quadrant number 3
Y = k/x for some fixed number constant k
7 = k/9
k = 63
so Y = 63/x
14 = 63/x
14 x = 63
x = 63/14 = 9/2
Answer:
phythaforean theorem:
1 . The square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
2. Find the square root to find the accurate length of the hypotenuse.
distance formula:
1. The distance formula is used to determine the distance, d, between two points.
distance = speed × time
Formula- d= √x2-x1)²+(y2-y1)²
2. It's used for :
-Finding the perimeter of polygons
-Finding the area of rectangles
-Finding the equation of a circle
