​

Answer 1

Answer:

Step-by-step explanation:

If a varies inversely as b - 4, and if a=5 when b=1/2.

To find : The value of a when b=-1​ ?

Solution :

If a varies inversely as b-4,

i.e.  

Where, k is constant of proportional

Substitute, a=5 when  

Now,  

Substitute b=-1,

Therefore, the value of a is 3.5.
