The correct answer is m=-2 (slope) and b=4 (y-intercept).
Answer: Option B is the cheaper deal (the 12 batteries for $14.76)
===========================================================
Explanation:
For the first deal we can say
3 batteries = 4.80 dollars
3/3 batteries = 4.80/3 dollars .... divide both sides by 3
1 battery = 1.60 dollars
The unit price for the first deal is $1.60 per battery.
----------------------------------
For the second deal we could say
12 batteries = 14.76 dollars
12/12 batteries = 14.76/12 dollars .... divide both sides by 12
1 battery = 1.23 dollars
The unit price for the first deal is $1.23 per battery.
This is the cheaper deal.
----------------------------------
So in short, you're dividing the total cost over the number of items to get the unit price.
Answer:
Step-by-step explanation:
In order to solve this, We will want to change it into an exponential form. Assuming that since we do not have a number beside log, It will be log base 10.
10^4=x
We can now solve for x.
This means that x= 10,000
