Answer:

Step-by-step explanation:
We can use the Polynomial Remainder Theorem. It states that if we divide a polynomial P(x) by a <em>binomial</em> in the form (x - a), then our remainder will be P(a). 
We are dividing: 

So, a polynomial by a binomial factor.
Our factor is (x + k) or (x - (-k)). Using the form (x - a), our a = -k. 
We want our remainder to be 3. So, P(a)=P(-k)=3.
Therefore: 

Simplify: 

Solve for <em>k</em>. Subtract 3 from both sides: 

Factor: 

Zero Product Property: 

Solve: 

So, either of the two expressions: 

Will yield 3 as the remainder.

Answer:
-2.65
Step-by-step explanation:
-1.2 - 1.45 = -2.65
you could just simplify fraction into decimal and use calculator
 
        
                    
             
        
        
        
Answer:
- Angle 'a' is an alternating exterior angle with one angle in the triangle and therefore congruent to one angle in the triangle formed by lines m, x, and y.
- Angles 'b' and 'c' are vertical angles with the other two angles in the triangle and therefore congruent to two other angles in the triangle 
Step-by-step explanation:
Vertical angles are angles that are equal to each other but in opposite direction. The angles b and c have vertical angles on the triangle Q while alternate exterior angles are equal angles that lie on different lanes cutting through an axis.
Angles on a plane can be congruent if they are vertical equals or alternating exterior angles. 
 
        
             
        
        
        
(-2,4) and (-4, - 8)
slope = (4 + 8)/(-2+4) = 12/2 = 6
answers are E and B
y - 4 = 6(x + 2)
y + 8 = 6(x + 4)
