Hello, this is a linear problem so we are working with y = mx + b
The problem tells us:
y = total cost
x = the megabytes of data that she used in a month
b = y-intercept, which is the initial value
The problem asks "Which part of the graph will represent the cost per megabyte of data used in each plan?"
It is asking for cost per megabyte... This is a rate. and m = slope = rate
So lets, reiterate.
y = total cost
x = the megabytes of data that she used in a month
b = y-intercept, which is the initial value
m = slope = rate = cost per megabyte of data used
Answer: The slopes of the two lines.

Step-by-step explanation:
hello :
(2x + 9)(3-z) = 0 means : 2x+9=0 or 3-z=0
x= -9/2 or z=3
Answer:
The average rate of change of the function from x=1 to x=2 will be: 10.5
Step-by-step explanation:
Given the function
at x₁ = 1,
f(x₁) = f(1) = -14/(1)² = -14/1 = -14
at x₂ = 2,
f(x₂) = f(2) = -14/(2)² = -14/(4) = -3.5
Using the formula to determine the average rate of change at which the total cost increases will be:
Average rate of change = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [-3.5 - (-14)] / [2 - 1]
= [-3.5 + 14] / [1]
= 10.5 / 1
= 10.5
Therefore, the average rate of change of the function from x=1 to x=2 will be: 10.5
In this question, you are given the width( 20 miles), the length(28 miles) and the height( 1 inch). You are asked to count the rain water volume which was going with formula length x width x height. But the unit asked is ft, so you need to convert them all. The calculation would be:
Water volume= length x width x height
Water volume= 20 miles x 5280ft/miles x 28 miles x 5280ft/miles x 1inch x 1ft/12inch
Water volume = 1300992000 cubic ft.
