What is the average rate of change for this function for the interval from x= 1

Mathematics
1 answer:
Usimov [2.4K]2 years ago
8 0

Answer:

  C. 8

Step-by-step explanation:

The average rate of change is the slope of the line between the two points of interest. It is given by the formula ...

  m = (y2 -y1)/(x2 -x1)

For points (1, 2) and (3, 18), the average rate of change is ...

  m = (18 -2)/(3 -1) = 16/2 = 8

The average rate of change between x=1 and x=3 is 8.

Find three consecutive integers that have an average of 53
saw5 [17]
Consecutive intergers are 1 away from each other so
numbers are
x,x+1,x+2

average is found by adding the numbers up and dividng the total by the number of numbers you have
so we add x+x+1+x+2 up and divide it by 3 (3 numbers)
x+x+1+x+2=x+x+x+1+2=3x+3
(3x+3)/3=53
[3(1x+1)]/3=53
3/3 times 1x+1=52
1x+1=53
subtract 1 from both sides
x=52

subsitute
x+1 is the second
x+2 is the third
x+1=52+1=53
x+2=52+2=54

numbers are 52,53,54
