6/7 is not a whole number.
6/7=0.857
If you want, you can round 0.857 to a whole number.
0.857 as a whole number would be 1.
Answer:
radius = 11
Step-by-step explanation:
The equation of a circle in general form is
x² + y² + 2gx + 2fy + c = 0
with radius = 
x² + y² - 20x + 14y + 28 = 0 ← is in general form
with 2g = - 20 ⇒ g = - 10
2f = 14 ⇒ f = 7 and c = 28, thus
radius = 
= 
= 
= 11
Answer:
4 parameters are necessary to specify all solutions and correspond to the number of free variables of the system.
Step-by-step explanation:
Remember that the number of free variables of a system is equal to m-rank(A) where m is the number of unknowns variables and A is the matrix of the system.
Since the system is consistent and the rank of the matrix is 3 then echelon form of the augmented matrix has two rows of zeros.
Then m-rank(A)=7-3=4.
