Answer:
C. 12
Step-by-step explanation:
Average rate of change = 
Where,
a = 1, f(a) = 3
b = 3, f(b) = 27
Average rate of change = 
Average rate of change = 
Average rate of change for the interval from x = 1 to x = 3 is 12
Given:
The location of point S on a coordinate plane.
To find:
The ordered pair for the point S.
Solution:
A point is defined as (x,y), where, |x| is the distance between the point and y-axis, and |y| be the distance between the point and x-axis. Signs of coordinates depend on the quadrant.
From the given graph it is clear that,
Distance between S and y-axis = 3.5
Distance between S and x-axis = 5.5
Point S lies in 3rd quadrant, it means x- and y-coordinates are negative.
Therefore, the ordered pair of point S is (-3.5,-5.5).
The equation of the line is x=2
Answer: 3.4
Step-by-step explanation:
i got this problem on delta math
First you have to get the number on the right 40 to equal 100 so do 40x2=80- +40x1.5= 100
Then do the same thing to the first number 8 so 8x2=16+8x1.5=20
then you have 20/100 right so then that number over 100 is the percent that you get ^-^ 20%
