Answer:
The average slope is 8.
Step-by-step explanation:
Let <em>f</em> be defined on the closed interval [a, b]. The average slope of <em>f </em>between a and b is the quotient
average slope = 
To find the average slope of the function 
on the interval [-1, 3] you have to evaluate your function in the interval and then divide by the interval.
So,
The average slope is 
The only one that wouldn’t change the y-value is a reflection across the y-axis.
Answer:
1 : 2 : 5
Step-by-step explanation:
20 : 40 : 100 ( divide each part of the ratio by 20 , the HCF of 20, 40, 100 )
= 1 : 2 : 5
456÷100=4.56
How to check your work: 456÷4.56=100
