Answer: 8
Step-by-step explanation:
We are going from a smaller triangle to a larger triangle, so the scale factor is greater than 1.
We know scale factor = (image)/(preimage), so the scale factor is 32/4 = 8
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Total interior angles in a triangle=180 degrees
That is: 3x + 10 + 5x - 1 + x =180 
9x+9=180
9x=180-9
9x=171
x=171/9
x=19
Therefore 
Angle A =67 degrees
Angle B= 94 degrees 
Angle C = 19 degrees 
 
        
             
        
        
        
Answer:
y = -4x - 6
Step-by-step explanation:
12x + 3y = -18
Solve for y.
3y = -12x - 18
y = -12/3 x - 18/3
y = -4x - 6
