A line perpendicular to y = 2x - 1 must have the slope -1/2 (negative reciprocal of 2).
Thus, the eq'n of the new line is y+2 = (-1/2)(x+2).
 
        
             
        
        
        
The property that is preserved under dilation is the similarity. The answer is letter A. Dilation of a figure starts from the very center of it and then continually increased or decreased depending on the desired size. It is similarity that is under dilation because no matter how big or small the size of the figure is, it has a similar feature from the original one.
        
             
        
        
        
Answer:
40%
Step-by-step explanation:
You can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 6 and 15 using
GCF(6,15) = 3
6÷315÷3=25
We know that
25
is the same as
2÷5
Then using
Long Division for 2 divided by 5
gives us
0.4
Converting our number to a percentage:
0.4×100
=40%
