Step-by-step explanation:
To get the inverse, swap the x- and y-variables, then solve for y. We should have the equation: 
Solving for y:
because
or 
So on interchanging the variable, we get the equation:
Answer:
2
Step-by-step explanation:
24/ 11 = 2 2/11
so, we have 2 and 2/11
11x2 = 22 + 2 = 24
5 because the highest power= degree of the function
10% of what is 9...
0.10x = 9
x = 9/0.10
x = 90.....he has 90 all together
