Answer:
Step-by-step explanation:
The function must be factorable.
For example, x^2 + x - 6= 0  factors to (x + 3)(x - 2) = 0 so the roots are -3 and 2.
x^2 + x - 7 = 0  will not factor so you need another method to solve this.
 
        
             
        
        
        
All you need to do is pull out the common factor of

Answer:
Step-by-step explanation:
The center of the circle whose diameter has endpoints (18, -13) and (4, -3) will be the midpoint of the coordinates.
The ormua for calculating mid point is expressed as;
M(X,Y) ={(x21+x2/2, y1+y2/2}
X= x1+x2/2
Y = y1+y2/2
From the coordinates
x1 = 18 x2 = 4
X= 18+4/2
X = 22/2
X = 11
y1= -13, y2= -3
Y = -3-13/2
Y = -16/2
Y = -8
Hence the required centre will be at (11,-8)
 
        
                    
             
        
        
        
Answer:
Reflection over y-axis
Step-by-step explanation:
We know that with a reflection of the x-axis, we flip the value of the y value
But since the y-values in Q3 and Q4 are both negative, we know that can't be the case
So it has to be a reflection over the y-axis where the x-values are flipped
