Answer:
   x in {-6, -2, 4}
Step-by-step explanation:
The zero product rule tells you that a product will be zero if and only if one of the factors is zero. These binomial factors are zero when x has a value that is opposite the constant of the binomial.
   x +6 = 0   ⇒   x = -6
   x -4 = 0   ⇒   x = 4
   x +2 = 0   ⇒   x = -2
The zeros of the function are the x-values -6, -2, and 4.
 
        
             
        
        
        
Answer:
The answer is 30 
Step-by-step explanation:
If you were to do 50% of 30, it would be 15 students that are girls. There's 18 students that are girls though, so the extra 10% would make 18 students in the class girls. The remaining 40% would be 12 boys. So basically you're taking 10% from one side and putting it in the other because 50% of 30 is 15 (well this is at least how I would do it, I don't know how others would do it though)
 
        
             
        
        
        
Look at the first line:  y = (3/5)x - 3.  What happens if you multiply each term by 5, to eliminate the fraction?
5y = 3x - 3
Compare this to the second equation, 
5y - 3x = -10, or 5y = 3x - 10.
The coefficients of x and y (as 3 and 5 here) determine the slope of a straight line.  Since 5y = 3x is present in both equations, the two lines MUST be parallel.
y = 4
4y = 6   =>   y = 6/4
y+4 and y =3/2 are both horizontal lines.  Since they are horiz., they are parallel.
