To find the inverse of the the function, it must be arranged in such a way that the independent variable be on the left side and the dependent variable on the right. So,f(x) = y = 3x/ (8 + x)y (8 + x) = 3x8y + xy = 3x8y = 3x - xy8y = x (3 - y)8y / (3-y) = xx = 8y / (3 -y)
Therefore,f-(x) = f(y) = x = 8y/ (3 - y)
Ya, can't help if you don't show the questions.
Answer:
x=6,y=0
Step-by-step explanation:
2x+y=12
3x-y=18
5x=30
x=6
6(3)-y=18
18-y=18
y=0
Add all of the like terms together then solve it like a normal equation.
