When you see that something is to the power of a negative number, it is another way of saying 1 over.
Answer:
(x+8)^2+y^2=16
Step-by-step explanation:
The equation for a circle in center-radius form is
(x-h)^2+(y-k)^2=r^2
where (h,k) is the center and r is the radius.
We are given the diameter is 8 so the radius is 8/2=4.
We are also given (h,k) is (-8,0).
The equation for the circle is
(x--8)^2+(y-0)^2=4^2
(x+8)^2+y^2=16
Let A and B represent the governor's salaries of states A and B, respectively.
A - B = 53,435
A +B = 290,395
Add these two equations to eliminate B.
2A = 343,830
A = 171,915
B = A -53,435 = 118,480
The governor of state A has a salary of 171,915.
The governor of state B has a salary of 118,480.
