Number of long distance calls made = m
Total phone bill = $3.40 = 340 cents
Cost per minute for long distance call = 3.3 cents
Then
<span>3.3m = 3.40
On solving we get
m = 340/3.3
= 103 minutes
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the first option. I hope the answer has come to your help.</span>
So if you didn't know x^2 + y^2 = r^2 is the equation of a circle where the center is at the origin. It is usually written as (x-h)^2 + (y-k)^2 = r^2. So if we are moving it to the left by 8 units we write:
(x+8)^2 + (y-k)^2 = 16
Next we move it 3 units down, so we get:
(x+8)^2 + (y+3)^2 = 16
That is your answer. Hope this helps! :D
Hello!!!
The Graph's Answer is below
<u>Nicole's Pattern Ian's Pattern Coordinate's Plane </u>
1 0 ( 1,0)
5 1 (5,1)
17 3 (17,3)
53 7 (53,7)
161 15 (161,15)
In order to get these answers, you start with 1 one Nicole's equation, and mutliply by 3, which gets you three. You then add two, which gets you five, after this, you continue to add Nicole's answer by three, then add five.For Ian's answer,you start with 0,then you add 1/2, which gives you .5 After you have this .5 you multiply by 2,which gives you one whole, you continue to add a half and mutliply by 2 for each answer. Nicole's answer is X,which means it is used first in our parentheses ( ),while ian's is Y and is used second.
I HOPE THIS HELPS! Good luck on your assignment and let me know if you need help with anything else <3!

Answer:
The rate of change in gasoline is 0.2$ per month.
Step-by-step explanation:
Given that Gas prices have increased steadily from $2.35 per gallon to $3.95 per gallon in 8 months.
Increase 'steadily' means the rate of change is the same throughout the 8 months.
let x represents the time in months, and y represents the gas price
so
at x₁ = 0, y₁ = 2.35
at x₂ = 8, y₂ = 3.95
Let us find the slope or rate of change using the formula
Rate of change = slope = m = [y₂ - y₁] / [x₂ - x₁]
= [3.95 - 2.35] / [8 - 0]
= 1.6 / 8
= 0.2 $ per month
Therefore, the rate of change in gasoline is 0.2$ per month.
