Answer:
33
Step-by-step explanation:
f(x) = 4x-3
Let x= 9
f(9) = 4*9 -3
36-3
33
0.1y = 3x^2
divide each side by 0.1
y = 3x^2/0.1
factor the right side to get y = 30x^2
this can't be written in the form y = kx so y does not vary directly with x
so there is no constant of variation.
The first one because just look which fraction is equivalent
