Question

Given that y is inversely proportional to x. Complete the following table
x
4
60
?
y
7.5
?
12
​

Answer 1

Step-by-step explanation:

We have to check if the numbers are inversely proportional

For this we know that two numbers x and y are inversely proportional is y=

x

1

So, for x and y to be inversly proportional xy=Constant

6×9=54

10×15=150

14×21=294

16×24=384

Since the values obtained are not equal

∴x and y are not inversely proportional.

Answer 2

Answer:

x. 4. 60. 2.5

y. 7.5. 0.5. 12

Step-by-step explanation:

given that x is inversely proportional to y

hence x=k/y where k is constant

Xy=k

to find k let x=4 ; y=7.5

k=(4)(7.5)

k= 30.0

to find y where x =60 is

60y=k

y=30/60

y=1/2=0.5

to find x where y = 12 is

12x=30

x=30/12=5/2=2.5

hence

x

4

60

2.5

y

7.5

0.5

12
