To find the inverse function, interchange the variables and solve for y.
h^-1 (x) = -9 - 3x/2
100% - 14% = 86%
86% of what gives you 559
559 * 100 = 55,900/86 = 650
650 students in total
650 - 559 = 91
Solution: 91 students failed
Let's break down all the information we receive from the question.
One pair of shoes= three times as much as a scarf
One pair of shoes and one scarf= $32
We need to make an equation where 3s= pair of shoes and s=scarf. We then need to put one pair of shoes + one scarf = 32.
3s+s=32
Now add.
4s=32
You could use 4s=32 (or 32÷4=s).
The new size of cube's side is 6. V new cube = 6*6*6 = 216
