When x=42 that means it is 8x6 so that means that the y = 120 becuase its 20x6
answer= y=120
F(x) = 6x + 5
g(x) = 6x - 5
f(g(x)) = 6(6x - 5) + 5 = 36x - 30 + 5 = 36x - 25
g(f(x)) = 6(6x+ 5) - 5 = 36x + 30 - 5 = 36x + 25
f and g are not inverse of each other.
Answer:
20:15
Step-by-step explanation:
baiscally add 4:3
4+3=7
then take the total of 35 and divide it by 7 you'd get 5.
4x+3x=35
7x=35
1x=5
4x=5×4=20
3x=5×3=15
4:3 therefore would be 20:15
