Answer: E. (x+5)^2 + (y-5)^2 = 9
Step-by-step explanation:
The equation of a circle is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius.
We are given that the center is (-5,5), which means that h = -5 and k = 5.
We are also given that the radius (r) = 3, which means r^2 = 9.
Therefore, the equation should be (x-(-5))^2 + (y-5)^2 = 9.
--> (x+5)^2 + (y-5)^2 = 9
Answer:
(-2, 1)

(-5 + 3),(2 -1)
Answer:
Step-by-step explanation:
t trees divided equally into 46 rows
If f(X)= 7x +5/3 - x =6x +5/3
y= 6x +5/3
6x= y-5/3
f^-1(y)=x=(y-5/3)/6
So we can write
f(f^-1(y))= f((y-5/3)/6) = 6 (y-5/3)/6 +5/3= y-5/3+5/3= y
The same result can be obtained for f^-1(f(x))=x
If the function is f(x)= 7x +5/(3-x) then it is not invertible since it is not injective (pictures)
15/8 = 75/40
2/5 = 16/40
7/8 = 35/40
75/40 + 16/40 - 35/40=
40/40 + 16/40 = 56/40
your answer is 1 16/40
simplest form: 1 2/5
hope this helps
