Answer:
(A)
Step-by-step explanation:
Answer:
Step-by-step explanation:
So we have the function:
To find the inverse of a function, switch f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:
Add 5 to both sides:
Multiply both sides by 4:
And we're done!
Hope this helps!
Let smaller no be x and bigger be y
- x+y=39--(1)
- 3x=y+81
- y=3x-81
- y=3(x-27)--(2)
Put it in eq(1)
- x+3(x-27)=39
- x+3x-81=39
- 4x=81+39
- 4x=120
- x=30
Now
The numbers are 9 and 30
