Answer:
Step-by-step explanation:
The value of y varies directly with x. When y = 75, x = ½ . What is the value of y when x is 2 ¼ ? A. 168.75 C. 66.67 B. 16.67 D. 337.5
y ∝x
y = kx
k = y/x
The answer is 56.25. You multiply 12.20 by 9 and then you get 112.5 . Then you get 112.5 and divide it by 2 and then you get 56.25

The next number is 27 because it is decreasing by 9 each time
The average rate of change between the interval x = 0.5 to x = 3.5 is: 5.
x = 3.5 represents 3.5 hours after noon.
<h3>How to Find Average Rate of Change Over an Interval</h3>
Given an interval of x = a to x = b, the average rate of change over the given interval of a function can be calculated using the formula below:
Given table representing the function as shown in the image attached below, let's determine the average rate of change for x = 0.5 to x = 3.5.
a = 0.5
f(a) = 47 (from the table, when x = 0.5, y = 47)
b = 3.5
f(b) = 62 (from the table, when x = 3.5, y = 62)
Plug the values into
Average rate of change =
Average rate of change = 5
x = 3.5 represents 3.5 hours after noon.
