The density curve must satisfy two important conditions.
These two conditions are:
1- The total area under the density curve MUST BE equal to 1.
     (Area total = 1)
2- Every point that is on the curve must have a vertical height that is equal to or greater than zero
(vertical height for each point ≥ zero)<span>
</span>
        
             
        
        
        
Answer:
Step-by-step explanation:
Multiplying Equation A by (1/3) and adding the result to Equation B will do the trick.  Let's actually solve the problem!
Equation A:  (5/3)x + 3y = 12
Equation B:    4x     -  3y = 8
                     ---------------------------
                      (5/3 + 12/3)x = 15        Note how this has eliminated the variable
                             (17/3)x = 15           y.
                                    x = (3/17)(15)

Answer:
(x+3)( 3x^2 +5)
Step-by-step explanation:
3x^3+9x^2+5x+15
Split into two groups
3x^3+9x^2     +5x+15
Factor 3x^2 out of the  first group and 5 out of the second group
3x^2 ( x+3)  + 5(x+3)
Factor out x+3
(x+3)( 3x^2 +5)
