Answer:

radius = 1

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 2)² + (y + 3)² = 1 ← is in standard form

with r² = 1 ( take the square root of both sides )

r = $\sqrt{1}$ = 1

James pays $120.00 for golf clubs that are on sale for 20% off at Golf Pros. At Nine Iron, the same clubs cost $8.00 less than t

Misha Larkins [42]

The original price of the clubs will be $135.

If the clubs at Nine Iron are $8 less than Golf Pros, they are 112.
120 - 8 = 112

Now, we just have to find the original price. We can write and solve the equation below to find the original price.

x (0.83) = 112 Divide both sides by 0.83

x = $135
