$(x-1)^2+(y+1)^2=\frac{1}{4}$

Step-by-step explanation:

The equation of a circle with center (h,k) and radius is given by (x-h)^2+(y-k)^2=r^2 .

What we're given:

of 1/2Center at (1, -1)

Substituting given values, we get:

$(x-1)^2+(y-(-1))^2=\frac{1}{2}^2,\\\boxed{(x-1)^2+(y+1)^2=1/4}$

There's a flat fee of $15 and a charge of $0.50 per mile. So we can write:

Where 'y' is the total cost of renting the car and 'x' is the amount of miles the car was used.

Write the equation of a circle that has a radius of 1/2 and a center at (1, -1), O (x - 1)^2 + (y - 1)^2 - 1/2
O (x - 1)^2 + (y +1)^2 - 1/4
O (x+1)^2 - (y + 1)^2 - 1/4
O (x + 1)^2 + (y - 1)^2 = 1/2
