Answer:
variable
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
Step-by-step explanation:
(h,k) center point
(-6,9) is the center point
h=-6
k=9
radius or r=3
Standard form is (x-h)^2+(y-k)^2=r^2
Equation of the circle is (x+6)^2+(y-9)^2=9
Answer;
In the first column, 35 chickens, and 6 horses.
In the second column, 7 chickens, and 20 horses.
In the third column, 27 chickens, and 10 horses.

Answer:
y=10.75
Step-by-step explanation:
46 + 1) + y = 5(y - 1) +9
47+y=5y-5+9
47+y=5y+4
Collect like terms
47-4=5y-y
43=4y
Divide by 4
43/4=4y/4
43/4=y
y=10.75
