Answer:
(y+1)/5
Step-by-step explanation:
you meant f^-1(x) ?
let y= 5x-1
Make x subject of formula
y+1=5x
x=(y+1)/5
f^-1(x)=(x+1)/5 replace y by x

Answer:
x = 2 m
y = 30°
Step-by-step explanation:
The side lengths of ΔDEF are 3/9 = 1/3 of those of ΔABC.
x = DF = 1/3(AB) = (1/3)(6 m)
x = 2 m
__
Angle measures of ΔDEF are the same as those of the corresponding angles of ΔABC.
y = ∠B = ∠E = 30°
y = 30°
