The only things you can factor out of here is a 3 so you are left with:
3(y-6)
Hope that helps.
15% - 40. -25 = 1500 percent take out the zero because they have zero value and your left with 15 which is 15%
Y= arcsin(x) is equivalent to sin(y) = x
we know that -1≤x+1, hence the range of y is: -π/2≤y≤+π/2
If i'm correct. it should be $10,022.40
The number 6 could replace the gap :)
