First make x the subject:-
3x = F(x) + 4
x = (F(x) + 4) / 3
f(-1(x) = (x + 4) / 3 answer
To do 130% increase you multiply by 1.3 so you do 810 × 1.3 = 1053
Well first you have to make the denominators equal by finding a common denominator. in this case 21, but whatever you do to the bottom you do to the top. so 1/3 times 7/7 equals 7/21 and 1/7 times 3/3 equals 3/21.
so how many 7/21 cups of ice cream can you make from 3/21 i think about none but remember i could be wrong
Step-by-step explanation:
use CAH method (Cos angle = adjacent/hypotenuse)
Given adjacent = 5
Hypotenuse = 12,

Answer:
The answer is 2 1/2 or in mixed form 5/2
Hope I helped :)
