Answer:
D.
Step-by-step explanation:
1) the domain is x∈[0;+∞);
2) the solution is:

3) finally, the solution with the domain is:
x∈[0;100].
-9T means -9 x T
So if T is equivalent to 4,
you should do:
-9 x 4 = -36
J= -36
1 is wrong there are two numbers greater than 4 but less than or equal to 6.
the first one was correct
Answer:
Center: (-1,8)
Radius: 1
The graph is attached.
Step-by-step explanation:
The equation of the circle has the form:

Where (h,k) is the point of the center of the circle and r is the radius of the circle.
The equation given in the problem is

Therefore:
h=-1
k=8
Then, the center is (-1,8) and radius is 1.
You can graph the circle with its center at the (-1,8) and a radius of 1 as you can see in the figure attached.
