X directly varies with y which means as x increases, y also increases. In this case, we represent a constant of proportionality of k.
Applying laws of <span> proportionality,
x =k y
48 = k* 16
k = 3
when y is 5
x = k y
x = 3* 5
x = 15</span>
Answer:
see explanation
Step-by-step explanation:
If f(x) and 
are inverse functions, then
f()(x) = x
Thus substitute x = (x) into f(x)
f(
)
= 5 ( ) - 6
= x + 6 - 6
= x
Thus f(x) and (x) are inverse functions
73, every number is in the same range except 73
The lowest value of the range of the function would be -2, as this is the lowest the y value goes
