Answer: d) 0 
Step-by-step explanation:
      With the inequality given, y ≤ -1, solutions are -1 and all numbers less than -1. We will check all the options to see which is not a solution.
      a) -3 ✓
            -> This is not our answer. -3 is less than -1.
      b) -1 ✓
            -> This is not our answer. -1 is equal to -1.
      c) -6 ✓
            -> This is not our answer. -6 is less than -1.
      d) 0 ✗
            -> This is our answer! 0 is not less than -1.
 
        
                    
             
        
        
        
Answer:
see below (I hope this helps!)
Step-by-step explanation:
The x seems to represent the number of months that Leslie has joined the gym for. When x = 0 (basically when she hasn't started using her membership), she pays 55(0) + 50 = $50 so we know that the 50 represents the one-time fee. The only thing missing is the monthly fee and since we haven't defined what the 55 means, we can conclude that the 55 represents the monthly fee. This makes sense because 55x is simply 55 times x, and since x is the number of months, 55 times that would be how much Leslie pays per month, otherwise known as the monthly fee.

Answer:
The only possible answer that is correct is the first one, x = -4.
Step-by-step explanation:
Simplify the given inequality as much as possible, and then substitute each of the given x values one by one to determine which is in the solution set.
9(2x + 1) < 9x - 18 becomes 18x + 9 < 9x - 18, which, if reduced by dividing all four terms by 9, becomes 2x + 1 < x - 2.
Simplifying further, we get x < - 3.  The only possible answer that is correct is the first one, x = -4.  -4 < -3 is true.
 
        
                    
             
        
        
        
You would need to see the rest of the equation to plug in 7 for x. Treat it as y=equation and replace any x with 7.
