Answer:
(x - 6)² + (y - 7)² = 4
Step-by-step explanation:
Equation of circle: (x - h)² + (y - k)² = r²
Given center(h,k) = (6,7)
h = 6
k = 7
Dimeter = 4 --
radius, r = 
= 2
(x - h)² + (y - k)² = r²
(x - 6)² + (y - 7)² = 2²
(x - 6)² + (y - 7)² = 4
Answer:
Regular price: $429
35% discount: 278.85
5% tax: $13.94
Final cost: 292.79
Step-by-step explanation:
regular price=$429
0.35(429)=150.15
429-150.15=278.85
35% discount amount: $278.85
278.85(0.05)=13.94
278.85+13.94=292.79
replace the value of x int eh equation
so 23x-1 becomes
23(1.1478)-1
23*1.1478 = 26.3994-1 = 25.3994
