Answer:
A. Yes; no value in the domain corresponds to more than one value of the range.
Step-by-step explanation:
There is no domain value that corresponds to more than one range value.
If you graph the ordered pairs on a coordinate plane, you cannot draw a vertical line that passes through more than one point.
Answer:
$400
Step-by-step explanation:
Let the initial total cost be represented = $X.
Hence, for 20 family members
= $ x/20 each .......1
Now that they are 25 members
= $x/25 each.......2
Each in the original group which is equation 1 owed $4 less.
That is,
x/20 - 4 ........ 3
Now equate 2 and 3
X/20 - 4/1 = X/25
Taking the LCM of both sides
X-80/20 = X/25
Cross multiply both sides
25( x-80 ) = 20x
25x-2000 = 20x
Collecting like terms
25x-20x = 2000
5x = 2000
Divide through by 5
X = 2000/5
X = 400
The total cost for the catered meal is $400.
To check if it was correct
Put 400 into equation 1 and 2 and then minus whatever you get from each other, you will get $4
From equation 1
400/20 = $20
From equation 2
400/25 =$16
$20-$16 = $4

To find the percent of the birdhouses occupied, divide the number of occupied birdhouses by how many birdhouses there are in total:
![4 \div 76 = 0.0526](https://tex.z-dn.net/?f=4%20%5Cdiv%2076%20%3D%200.0526)
Convert this decimal into a percentage by multiplying by 100:
5.26% of the birdhouses are occupied.
I know that the factors of 12 are 1, 2, 3, 4, 6, and 12
Therefore, the possible roots are 1, 2, 3, 4, 6, and 12
