Answer:
X=-3, Y=1
Step-by-step explanation:
Y=4x+13
Y=6x+19
4x+13=6x+19
-2x=6
X=-3
Y=1
 
        
             
        
        
        
Answer:  3/4,  because the probability of renting a comedy is 1/4
================================================================
Explanation:
We have 36+26+30+28 = 120 students. 30 of which rented a comedy.
The probability of renting a comedy is 30/120 = (30*1)/(30*4) = 1/4
The probability of not renting a comedy is 1 - (1/4) = 4/4 - 1/4 = (4-1)/4 = 3/4.
Or you could say that 1/4 = 0.25, so 1-0.25 = 0.75 which converts to the fraction 3/4.
If you had 4 people and 1 of them rents a comedy, then the other 3 hasn't rented a comedy.
 
        
             
        
        
        
Answer:
You got this just keep trying i know you can do it even if it is really hard
 
Step-by-step explanation:
 
        
             
        
        
        
It goes above the 3 because 7 does not go into 6
        
                    
             
        
        
        
Assuming that the equation is 3x^2+3x-6=0, then use the quadratic equation, (-b+- sqrt(b^2-4ac))/2a, with ax^2+bx+c as the original equation. so here we get (-3+-sqrt(9+72))/6 = (-3+-sqrt(81))/6 = (-3+-9)/6, = (-1+-3)/2 = 1 or -2. Plug in original to check.
