The 44 in 44,000 is indicating the value of the thousand (,000). Because it is a 44, it would be 44 thousand. The first 4 is the 10,000 digit, and the second 4 is the 1,000 digit. All together, it is 4 ten thousands, plus 4 thousands, making 44,000
        
                    
             
        
        
        
Answer:
a) Angle XBC = 55 because XY is parallel with BD
b) As given, XB = XC, so that triangle XBC is the equilateral triangle. 
As XBC is equilateral triangle, angle XBC is equal to angle XCB 
Angle XBC = 55° => Angle XCB = 55°
In a triangle, the total value of three corners are equal to 180°
So that: Angle XBC + Angle XCB + Angle BXC = 180°
=> 55° + 55° + Angle BXC = 180 °
=> Angle BXC = 70°
 
        
                    
             
        
        
        
Answer:
a. y = -5x + 4
Step-by-step explanation:
Given the following data;
Slope, m = -5
Intercept, c = 4
Mathematically, the equation of line is given by the formula; y = mx + c
Where;
m is the slope. 
x and y are the points
c is the intercept.
Substituting the given parameters, we have;
y = -5x + 4
