(4x-15)
(12x+3)

1 answer

To determine the value of x in order to make b parallel to d, we need to find the value of x that makes the two expression for b and d equal.

The expression for b is 4x-15, and the expression for d is 12x+3.

To make b parallel to d, their slopes must be equal.

The slope of the line represented by b is the coefficient of x in the expression 4x-15, which is 4.

The slope of the line represented by d is the coefficient of x in the expression 12x+3, which is 12.

For b and d to be parallel, their slopes must be equal.

Therefore, we set 4 equal to 12 and solve for x:

4x = 12
x = 12/4
x = 3

So, when x = 3, b is parallel to d.
