Answer:
C
Step-by-step explanation:
A function cannot have multiple y values for one x value.
Option A lists the y values of -8 and 10 for the x value of -4. Therefore this is not a function.
Option B lists 0, 5, 10, AND 15 all for -1. This can't be a function either.
Option C does not have two of the same x values for different results. Although both 0 and 9 give you the answer of 1 for the y value, this is perfectly okay in a function. This is your answer.
<span>I believe what you are looking for here is an expression. For this example, the cost of a pen will be represented by x. We know that a folder costs $1.15 more than a pen, so the cost of a folder will be represented by x+1.15. This question is asking for 6 pens, and so we multiply the cost of a pen (x) by 6 and get 6x. It also asks for 3 folders, and so we multiply the cost of a folder (x+1.15) by 3 and get 3(x+1.15). When you simplify that by multiplying the 3 by the x and then the 3 by the 1.15, you get 3x + 3.45. To get the total cost of 6 pens and 3 folders, add the two together for an answer of 6x + 3x+3.45. Simplify that by adding the two x's together and get 9x+3.45, where x is the cost of a pen.</span>
withdrawals are when cash is taken out from the account
Flora withdraws an amount of $75 at a time from her bank account
she makes 7 such withdrawals
one withdrawal she takes out - $75
then seven withdrawals leads to - $75 x 7 = $525
then overall change in her account has been a net withdrawal of $525
so the overall change in the account is -$525
There would be no money saved because they are both the same. 1.1% per month is the same as 13.2% per year since 1.1 multiplied to 12 (the number of months in a year) is 13.2. Therefore, no money could be saved either way. Hope this helps!
Answer:
The length of the runway = 12090 feet
Step-by-step explanation:
The formula involving the area of a rectangle is
![A=wl](https://tex.z-dn.net/?f=A%3Dwl)
here
Given
Area A = 1,934,400 square feet
Width w = 160 w
Length l = ?
Using the formula
![A=wl](https://tex.z-dn.net/?f=A%3Dwl)
substituting the values
1,934,400 = 160 × l
l = 1,934,400 / 160
l = 12090 feet
Therefore, the length of the runway = 12090 feet
