The answer is f(x)‐¹=(+/-)x+25+5
Answer:
You should buy from the first store
Step-by-step explanation:
Since there are 4 quarts in a gallon, we will need to multiply .80 by 8 to figure out how much it costs for 2 gallons. This will be $6.40 for the second store, and in order to find out how many the first store offers, we multiply 3 by two, which is six.
So, the first store charges $6.00 for two gallons, and the second store does $6.40 for two gallons of milk
Answer:
the cost for one pound before taxes is $4.52
Step-by-step explanation:
The computation of the cost for one pound before taxes is shown below:
= Paid a bill + amount - change amount
= $20 + 5 - $4.67
= $20.33
Now the cost of one pound would be
= Total amount ÷ number of pounds purchased
= $20.33 ÷ 4.5 pounds
= $4.52
Hence, the cost for one pound before taxes is $4.52
For this case we have that by definition, the area of a square is given by:
![A = l ^ 2](https://tex.z-dn.net/?f=A%20%3D%20l%20%5E%202)
Where:
l: It's the side of the square
We have, according to the statement data, that:
![l = 7z ^ 5 \ dm](https://tex.z-dn.net/?f=l%20%3D%207z%20%5E%205%20%5C%20dm)
Then, the area is given by:
![A = (7z ^ 5 \ dm) ^ 2](https://tex.z-dn.net/?f=A%20%3D%20%287z%20%5E%205%20%5C%20dm%29%20%5E%202)
By definition of power properties we have to:
![(a ^ n) ^ m = a ^ {n * m}](https://tex.z-dn.net/?f=%28a%20%5E%20n%29%20%5E%20m%20%3D%20a%20%5E%20%7Bn%20%2A%20m%7D)
So:
![A = (7z ^ 5 \ dm) ^ 2 = 49z^{5 * 2} \ dm ^ 2 = 49z^{10} \ dm ^ 2](https://tex.z-dn.net/?f=A%20%3D%20%287z%20%5E%205%20%5C%20dm%29%20%5E%202%20%3D%2049z%5E%7B5%20%2A%202%7D%20%5C%20dm%20%5E%202%20%3D%2049z%5E%7B10%7D%20%5C%20dm%20%5E%202)
Answer:
The area of the square is: ![49z^{10} \ dm ^ 2](https://tex.z-dn.net/?f=49z%5E%7B10%7D%20%5C%20dm%20%5E%202)
Answer:
