Yep that's the right answer man great job!
The correct answer is c because when I graphed each one the only one that passed through your given coordinate was that equation
<span>The
graph of y against x in inverse proportion is a rectangular hyperbola
but I don't see at all how this knowledge/observation is any help in
solving the problem.
Inverse proportion means that as x doubles y will halve and the equation
is xy = k where k is some number. A good example of inverse proportion
is speed and time taken over some fixed distance. In this case x could
represent the speed (mph) and y the time (h) and then k is the distance
in miles.
Since we know y=3 when x=2 we have xy = 6. Now it's easy to see when x=6 y=1.</span>
Answer:
682
Step-by-step explanation:
620, percentage decreased by - 10% (percent) of its value = 682
Multiply 2^(-5) by 2^6. The correct result is 2^1, or just 2 (inches).
