30 mph because if you do 60x 3 and 50x3, you get 180 and 150, then you subtract 180-150 and you get 30
Answer:
A. The two lines are neither parallel nor perpendicular.
Step-by-step explanation:
If the composite functions f(g(x)) and g(f(x)) both equal to x, then the function g is the Inverse function of f.
<h3>What is the inverse of a function?</h3>
A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y.
Let us take the Example.
Suppose f(x)= x/4 and g(x)=4x.
Let x=1
then f(g(x))= f(g(1))=f(4)=1
and g(f(x))=g(f(1))=g(1/4)=1
Here, f(g(x))=g(f(x))=1
Therefore , we can say that f(g(x)) and g(f(x)) are inverse of each other.

Answer:
Step-by-step explanation:
75/10
Answer:
9 sides
Step-by-step explanation:
Each interior angle of a regular polygon is 100 degrees larger than the exterior angle determine the number of sides of the polygon
Interior angle + exterior angle =
180°
Let x be the exterior angle.
Exterior angle = 180-x = 100 + x
= 180 - 100 = x + x
80 = 2x
x = 80/2
x = 40
Number of sides of the polygon =
= 360°/Exterior angle
Exterior angle = 40°
= 360/40 = 9 sides
