Answer:
x = 5; the slope is undefined
Step-by-step explanation:
A line perpendicular to the x-axis is a vertical line.
In a vertical line, every point has a different y-coordinate and the same x-coordinate. Since you want a line that is vertical and passes through the point (5, -3), then every point on the line must have x-coordinate 5 no matter what its y-coordinate is. The slope of a vertical line is undefined.
Answer: The equation is x = 5; the slope is undefined
 
        
             
        
        
        
Answer:
no solution
Step-by-step explanation:
Given
 (6x + 12) - 2(x - 7) = 19 ← distribute parenthesis on left side
(6x + 12) - 2(x - 7) = 19 ← distribute parenthesis on left side
2x + 4 - 2x + 14 = 19 , that is
18 = 19 ← not possible
This indicates the equation has no solution
 
        
             
        
        
        
I found the complete problem. 
If Alice divides it into two trapezoids, the area formula would be: A = [(a+b) / 2] * h 
Trapezoid 1 
A = [(7.5 + 15)/2 * 5 
A = (22.5/2) * 5 
A = 11.25 * 5 
A = 56.25 sq. ft
Trapezoid 2 
A = [(5 + 10)/2 * 7.5 
A = (15/2) * 7.5
A = 7.5 * 7.5 
A = 56.25 sq. ft
Total area = 56.25 + 56.25 = 112.50 sq. ft.
 
        
        
        
I think the answer is A. 7 5/6
