20% of $175 is $35. Divided between 5 people (35/5=7) would be 7. So each person should tip $7.
F(f-1x) will be equal to x
take a simple example
f(x) = 2x
so x = f(x) / 2
f-1(x) = x/2
f(f-1x) = 2 ( x/2) = 2 * x/2 = x
Answer:
A

Answer:
a. 56
b. 72
c. 64
Step-by-step explanation:
Answer:
Given all right triangles
<u>Use Pythagorean to find the missing side:</u>
- a² + b² = c², where c- hypotenuse
=1=
- x² = 6² + 3² = 45
- x = √45
- x = 6.7
=2=
- x² = 12² + 5² = 169
- x = √169
- x = 13
=3=
- x² = 2² + 5² = 29
- x = √29
- x = 5.4
