A circles equation is
(x – h)^2 + (y – k)^2 = r^2
The center is at the point (h, k)
The radius is r.
Your circles equation is:
(x – 2)^2 + (y – 8)^2 = 5^2
Answer:
i think its 20 too, tho good luck
Step-by-step explanation:
To solve this problem, we make use of the formula of
combination.
nCr = n! / r! (n – r)!
where n is the total number of subject teachers and r is
the number of subjects r = 1
For the English class n = 3
3C1 = 3! / 1! (3 – 1)! = 3
For the Algebra class n = 4
4C1 = 4! / 1! (4 – 1)! = 4
For the Biology class n = 2
2C1 = 2! / 1! (2 – 1)! = 2
The total number of different schedules would be the
product of the three combinations:
total combinations possible = 3 * 4 * 2
total combinations possible = 24
Answer:
x=1 y=-3
Step-by-step explanation:
given example: y=6x+3
y=-x-4
6x+3=-x-4
6x+x=-4-3
7x=-7
x=-1
6*(-1)+3=-3
y=-3
