Y=4x+1 is the answer to your question
        
             
        
        
        
Answer: D
Step-by-step explanation:

 
        
             
        
        
        
Since its x + 3 we use -3
-3| 2      1      -8      21           (these are the # without the x)
___________________
            -6     15     -21      
-------------------------------
    2      -5      7        0               
 
Drag the 2 down, multiple it by -3 to get -6 
1+(-6) = -5. -5 * -3 =15 . 15+(-8) = 7
7*-3 = -21. -21 +21 = 0 
Since last # is 0 we have a factor.
 factor is 2x^2 -5x -7 (we start with a power 1 less the original.)

If there must be LESS than 12 people in the tour group, then it would automatically take out the n>12 because n>12 represents n being MORE than 12, so your answer would be n<12. I hope you aren't totally confused, and good luck on the test!!! I am working on my math skills and I just did this quiz, so the answer is in fact, <. Make me brainliest please, would truly help.
