Answer: Without replacing
Step-by-step explanation:
If you don't replace the first red marble, it decreases the number of red marbles in the mix, making the proportion of blue marbles relatively larger. For example, if there were 5 red and 5 blue marbles, there would be a 50% chance of drawing a blue marble. If the red drawn is not replaced, there is a 5/9 chance of drawing a blue marble, or a 55% chance of drawing one.
 
        
             
        
        
        
Step-by-step explanation:
Given equations: 
        y  = x² + 3x - 29    ------ (i)
        y  = 2x - 9  ---------------- (ii)
Now to solve this problem, we must determine the value of x and y; 
  Equate equations 1 and 2; 
        x² + 3x - 29 = 2x - 9 
        x² + 3x - 2x - 29 + 9  = 0 
        x² + x - 20  = 0 
        x² + 5x - 4x - 20  = 0 
        x(x + 5 ) - 4(x + 5) = 0 
       (x - 4) (x+ 5) = 0 
        x  - 4  = 0 or x + 5  = 0 
        x  = 4 or x = -5; 
So;   solve for y now; 
      y = 2x - 9 
      input x  = 4 or x = -5; 
     y  = 2(4) - 9 or y = 2(-5) - 9
     y = -1 or y = -19
