Answer:
(x - 4)² + (y + 6)² = 5²
Step-by-step explanation:
rearrange the general equation as follows
collect the terms in x and y together and place the constant on the right side
x² - 8x + y² + 12y = - 27
add (half the coefficient of the x/y term)² to both sides
x² + 2(- 4)x + y² + 2(6)y = - 27
(x - 4)² + 16 + (y + 6)² + 36 = - 27 + 16 + 36
(x - 4)² + (y + 6)² = 25
(x - 4)² + (y + 6)² = 5² ← in standard form

well u can transfer the -5 in denominator to the right hand side
so x=1.2*(-5)
x=-6.0
Multiply his AGI by 7.5% to find the amount medical needs to meet before deducting:
46,000 x 0.075 = $3,450
He can deduct any amount over $3450.
Subtract that from his medical total to find the amount he can deduct:
5800 - 3450 = 2350
He can deduct $2,350.
