Answer:
D
Step-by-step explanation:
Slope formula: m = (y2 - y1) / (x2 - x1)
First coordinate: (1, 3)
Second coordinate: (3, 9)
m = (9 - 3) / (3 - 1)
m = (6) / (2)
m = 3
Option D: 
is the inverse of the function f(x) = 4x
Explanation:
Given that the function is 
We need to determine the inverse of the function.
<u>Inverse of the function h(x):</u>
The inverse of the function can be determined by interchanging the variables x and y and then solving the function for y.
Thus, the function is written as,
Interchanging the variables x and y, we have;
Dividing both sides by 4, we get;
Thus, the inverse of the function is
Hence, Option D is the correct answer.
Answer:
5 packages . .
Step-by-step explanation:
The ticket price was decreased by 8.75-6=2.75$
to know the percentage of decrease:
percentage=(fraction of decrease/total price) x 100
percentage = (2.75/8.75) x 100
= 31.4%
