Answer: x² + y² = 25
Step-by-step explanation: As we have x²+y²=25 (A) as options,
x-y=1 (B)
x+y=25 (C)
x²+y²=5 (D)
We can rule out B and C as they are not circles. Circles must be
(x - xc)² + (y - yc)² = r². They must have index 2.
We have then A or D.
As the circle must pass through (3,4), we can substitute as x=3 and y=4
(A) 3² + 4² = 9 + 16 = 25 ok
(D) 3² + 4² = 9 + 16 = 25 ≠ 5
So, it is A, x² + y² = 25

Answer:
Step-by-step explanation:
Answer:Yes
Step-by-step explanation:
The value of n which makes the expression true is - 9
Given the expression : 4(0.5n-3)=n-0.25(12-8n)
The value of n which makes the expression true can be obtained by solving for n ;
4(0.5n-3)=n-0.25(12-8n)
Open the bracket :
2n - 12 = n - 3 + 2n
Collect like terms :
2n - 2n - n = - 3 + 12
-n = 9
Divide both sides by - 1 to isolate n
Hence ;
n = - 9
The value of n which makes the expression true is - 9
