To write this it would be 20/x-3. I hope this helped. :)
The answer to your problem is 6 7/8.
The value of the function is x is 7 and 4 are 2 and 12 respectively
<h3>Function and values</h3>
Given the function of the variable x below;
f(x) = 12x+12/x²-1
If the value of x is 7, hence;
f(7) = 12(7)+12/(7)²-1
f(7) = 84+12/48
f(7) = 96/48
f(7) = 2
If the value of x is 4, hence;
f(4) = 12(4)+12/(4)²-1
f(4) = 48+12/15
f(4) = 60/5
f(4) = 12
Hence the value of the function is x is 7 and 4 are 2 and 12 respectively

Answer:
6 Chickens
Step-by-step explanation:
Let H represent the number of horses and C represent the number of chickens. Since there are 32 legs altogether this means that on equation to use would be given by:
2C + 4 H = 32 (Eq. 1)
Another equation can be made from the fact that there are 11 heads or 11 animals altogether which can be written as:
C + H = 11 (Eq. 2)
From Eq. 2, solve for the number of chickens:
C + H = 11
C = 11 - H (Eq. 3)
Substituting Eq. 3 in Eq. 1, the number of horses can be determined:
2 C + 4 H = 32
2 ( 11 − H ) + 4 H = 32
22 − 2 H + 4 H = 32
2H = 32 − 22
2 H = 10
H = 5 Eq.4
Putting Eq.4 in Eq.1
2C + 4*5 = 32
2C = 32 - 20
2C = 12
C = 12/2
C = 6
