Answer:
- Center = (3, 0)
- Radius = 3
- Graph = see below
Concept:
Here, we need to know the idea of the circle equation.
Circle equation: (x - h)² + (y - k)² = r²
(h, k) = center
r = radius
x = variable
y = variable
Solve:
<u>Given expression </u>
(x - 3)² + y² = 9
<u>Find the point of the center</u>
(h, k) = 
<u>Find the length of the radius</u>
r² = 9
Hope this helps!! :)

Answer:
A) −31+2n=−55
Step-by-step explanation:
2n−31=−55
2n−31+31=−55+31
2n=−24
2n over 2=-24 over 2
n=-12
Answer:
x=13/2
Step-by-step explanation:
3/4x=4 7/8
x= 4 7/8 divided by 3/4
x=13/2
check
3/4*13/2=39/8
=4 7/8
The area of the shaded region is 12m. I am not a 100% sure.
Answer:
120/99 is the answer.
Step-by-step explanation:
It has a line over it means that after the point there are infinite numbers of 21.
•Multiply 1.212121... with 100
we get 121.212121...
•Subtract it with the original one
121.212121.. - 1.212121... = 120.000.. = 120
Write it as an equation :-
Let the fraction be x.
(100×x) - x = 120
100x-x = 120
or, 99x = 120
so, x = 120/99
