199.95*.3=59.99 (rounded)
199.95-59.99=140

3500
The correct answer should be A
We can re-write the equation √(1-x) - 2y = 2 → - 2y = 2 - √(1-x)
→ 2y = - 2 + √(1-x) → and y = [ - 2 + √(1+x)]/2
Tis function "exists" as long as the radical is > or = to zero:
1+x > or = 0 → x>-1
{x ∈ R for x> =0}
I hope this helped you just follow the steps if you need help again
