45.00x +17.99 = 422.99 (Setup Equation)
45.00x = 405 (Subtract 17.99 from both sides)
x = 9 (Divide both sides by 45.00)
Answer:
(x - 3)² + (y - 3)² = 4
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
Here (h, k) = (3, 3) and r = 2, thus
(x - 3)² + (y - 3)² = 4
Yes, 14 is correct.
15: 3^4 - 4
16: 7n - 6
17: n^2 / 8
18: 3n x 9
