Answer:
Undefined
Step-by-step explanation:
If a linear equation is organized in the form x=[a number], we know straight away that this line is a vertical line. This form is actually , where
is the x-intercept of the line. Vertical lines do not have a y-intercept because they are parallel to the y-axis.
The slope of vertical lines is undefined.

Cost spent by Tracey for her clothes = 38$
Let assume the spending by Daniel is x
<u>Given</u>:
Given that two lines are intersecting at the point.
The angles (3x - 8)° and (2x + 12)° are the angles formed by the intersection of the two lines.
We need to determine the equation to solve for x and the value of x.
<u>Equation:</u>
The two angles (3x - 8)° and (2x + 12)° are vertically opposite. Hence, the vertically opposite angles are always equal.
Hence, we have;
Hence, the equation is
<u>Value of x:</u>
The value of x can be determined by solving the equation
Thus, we have;
Subtracting both sides of the equation by 2x, we get;
Adding both sides of the equation by 8, we get;
Thus, the value of x is 20.
Hence, the equation and the value of x are
Thus, Option D is the correct answer.
