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.

Answer:
k = 3
Step-by-step explanation:
Given
4.5 + 1.5k = 18 - 3k ( add 3k to both sides )
4.5 + 4.5k = 18 ( subtract 4.5 from both sides )
4.5k = 13.5 ( divide both sides by 4.5 )
k = 3
I think it's 0 since anything multiplied by 0 is, well, 0! No matter what the sign is. I believe the correct answer is 0 :)
Hey buddy

Let her monthly salary be x
1/8x = $65
x = $65 × 8 = $520
Her weekly pay is $520 ÷ 4 = $130
