Answer:
x = 80
Step-by-step explanation:
1x + 0.2x = 96
1.2x = 96
Divide both sides by 1.2
x = 80
Answer:
6f = 24
f = 4
Step-by-step explanation:
Answer:
Only five points
Step-by-step explanation:
For such an question
Answer:
see explanation
Step-by-step explanation:
To show f and g are inverses we require to show that
f(g(x)) = x and g(f(x)) = x
f(g(x))
= f(6x - 4)
=
=
= x
-----------------------------------------------------------------------------
g(f(x))
= g(
)
= ( 6 ×
) - 4
= x + 4 - 4 = x
-------------------------------------------------
Hence f and g are inverses
