Answer:
option (c) is correct.
d < 6
On number line this is shown as attached below.
Explanation:
Given inequality 4d - 6 < 18
We have to plot the inequality and check out of given graph which graph satisfies the Given inequality 4d - 6 < 18
Consider the given inequality 4d - 6 < 18
Add 6 both sides, we have,
4d - 6 + 6 < 18 + 6
Simplify we get,
4d < 24
Now, divide both side by 4, we have,

Simplify , we have,
d < 6
On number line this is shown as attached below.
Thus, option (c) is correct.
