The correct answer for the exercise shown above is:
 zero (0)
 The explanation is shown below:
 1. You have the following expression given in the problem above:
 7/6a
 2. By definition, <span>the nonpermissible replacement for a is the value that make the denominator equal to zero.
 3. Keeping this on mind, you have:
 7/6a=7/6(0)=7/0
 Therefore, as you can see, the answer is: zero (a=0).

Answer:
2 n - 2 = n - 38
Step-by-step explanation:
Two fewer than "a number doubled"
2n-2 = n-38
 
        
             
        
        
        
Answer:
   the dilated coordinates are (12, 9), (6, 9), (12, -6), (6, -6)
Step-by-step explanation:
The dilation factor multiplies each coordinate value when the center is the origin.
__
   (8, 6) ⇒ 1.5(8, 6) = (12, 9)
   (4, 6) ⇒ 1.5(4, 6) = (6, 9)
   (8, -4) ⇒ 1.5(8, -4) = (12, -6)
   (4, -4) ⇒ 1.5(4, -4) = (6, -6)
