Step-by-step explanation:
The given inequality is

Subtract 10 from both sides


Divide both sides by 5 to get:

We draw a closed circle at 5 and draw the arrow to the left.

Answer:
6
Step-by-step explanation:
Given I varies inversely with R then the equation relating them is
I =
← k is the constant of variation
To find k use the condition R = 12 when I = 3
k = IR = 3 × 12 = 36
I =
← equation of variation
When I = 6, then
6 =
, hence
R =
= 6
