Answer:
15 degrees
Step-by-step explanation:
Since ABD is a right angle it equals 90 degrees
ABC is 75 degrees
ABC + CBD = ABD
75 + CDB = 90
Subtract 75 from each side
75-75 + CDB = 90-75
CDB = 15
The other angle is 15 degrees
 
        
                    
             
        
        
        
Answer:
If a quadratic function is not discriminating at 0, it does not have any real roots and it does not intersect the x-axis in the parabola it serves.
Step-by-step explanation:
The equation has no true solution if the discriminant is less than 0.
 
        
             
        
        
        
Answer:
-1/2
Step-by-step explanation:
slope is rise over run 
or y change divided by x change
to find the slope you need to find points on the graph that meet exact points on the graph
i see (0,1) and (2,0)
to find slope without graph it would be (y2-y1)/(x2-x1)
in this case (0-1)/(2-0)
=-1/2
with graph you can count that it goes down -1 squares and to the right 2 squares
hope this helps

Answer:
D
Step-by-step explanation:
2y=10x
Divide both sides by 2.
y=5x
Now substitute this into the second equation.
