Suppose f(x) varies inversely with x and f(x)=3 when x=10. what is the value of f(x) when x=15 a=0.3 b=2 c=4.5 d=30 show me how you solved it i will mark brainliest if you show me.

you'll just earn points here

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
