18) Value of b is : b\geq  8

Option A is correct.

19) Option C is correct.

Step-by-step explanation:

18) We need to find the value of b.

The given equation is:

12b-46\geq 50

Solving to find the value of b:

12b-46\geq 50\\12b\geq 50+46\\12b\geq 96\\b\geq \frac{96}{12}\\b\geq  8

So value of b is : b\geq  8

Option A is correct.

19) We need to find the correct graph of the equation:

4y-2

Solving:

4y-2

The values of y will be less than three. As y < 3 so, the circle on y is not filled.

So. Option C is correct.
