Answer:
k=4
Step-by-step explanation:
-The constant of proportionality is defined as the ratio between two directly proportional variables.
-Given that B=4f
#The constant of proportionality is calculated as:
- the equation can be written in the form y=kx,
where y varies directly with x and k is the constant of variation:
Hence, B varies directly with f with a constant of proportionality k=4
64
Common denominator: 18
-14/18 + 11/18
= -3/18
Reduce:
-1/6
B.
there cannot be two of the same x value's. It would make it a circle on the graph, or something close to that, which isn't a function.
