Step-by-step explanation:
GI is made up of the segments GH and HI. In other words:
We know that GH is 2 and GI is 7. Substitute:
Subtract 2 from both sides:
So, our answer is B.
And we're done!
Answer:
25
Step-by-step explanation:
Since y varies inversely with x, the relation between y and x will be:
Introducing the proportionality constant, we can write:
Using the first set of given values of x and y, we get:
This means, the relation between y and x is:
We have to find y if x = 20. Using this value in above equation, we get:
Thus y would be 25 if x is 20.
