Answer:
y = 1/3
Step-by-step explanation:
2/3 (6y - 4) = - 4y
2(6y-4)/3 = -4y
2(6y-4) = (-3)(4y)
y = 1/3
 
        
                    
             
        
        
        
Y = 3x + 0 is what i got though check my math to be sure 
        
             
        
        
        
First substitute .5x in for y to get a solvable equation. You should get 6x+8(.5x)=30. Then multiply 8 times .5 to get 6x+4x=30. Then combine like terms (6x+4x) to get 10x=30 and divide both sides by 10 to get x=3. Then plug this x value (3) into the other equation (y=.5x) to find the value of y. Y=.5(3) so y=1.5. Therefore the answer is B.

Answer:
D. (x+2)(-8x+70)
Step-by-step explanation:
-8x^2+54x+140 
Factor out -2
-2(4x^2+27x+70) 
Factor
-2(x+2)(4x-35)
Option D is the same answer if we multiply -2 in the second term
(x+2) (-8x+70)
