Answer:
Step-by-step explanation:
Yeah the equation is change in y over change in x; change in is represented with the delta sign, so y2-y1/x2-x1
Answer:
No, this is not a whole number. See how it has a decimal point? That's how you know if it is a decimal.
:)
14) The answer is a) y = 2x. 2 is the slope and the line does not cross over the Y axis in this picture so there is not a Y-intercept you can see.
15) You pretty much just estimate. On the graph when you find 50 minutes and go up its around 140. 50 x 2 is 100 minutes. so just multiply 140 by 2 and its 280 so just round to the closest one.
Answer:
![Change = (Paid*100) - Price](https://tex.z-dn.net/?f=Change%20%3D%20%28Paid%2A100%29%20-%20Price)
Step-by-step explanation:
First of all we need to know the relation between 1 dollar and 1 cent in order to express everything in the units required in the question.
We know that
, so the amount paid for the item with single dollars has to be multiplied by 100 to express its value in cents.
![Paid_{cents}=Paid_{dollars}*100](https://tex.z-dn.net/?f=Paid_%7Bcents%7D%3DPaid_%7Bdollars%7D%2A100)
Now that we have everything in cents, we can make the subtraction:
![Change_{cents} = Paid_{cents} -Price_{cents}](https://tex.z-dn.net/?f=Change_%7Bcents%7D%20%3D%20Paid_%7Bcents%7D%20-Price_%7Bcents%7D)
Replacing the value in cents we get:
![Change = (Paid*100) - Price](https://tex.z-dn.net/?f=Change%20%3D%20%28Paid%2A100%29%20-%20Price)
Answer: yes, indeed it is i forgot how it is but it is
