Answer:
Step-by-step explanation:
use the comparison method
3x + 1 = 3x - 3
1 = -3 
the expression is false for any value of x and y , so there no solution
 
        
             
        
        
        
(3/4) /(4/5) = x/1
cross multiply
4/5x = 3/4
x = 3/4 * 5/4
x = 15/16 tons of pebbles are needed to cover the entire garden
        
                    
             
        
        
        
<span>the Slope would be (m) =<span>-6</span></span>
        
                    
             
        
        
        
The general form of a quadratic equation is that which is expressed in a form,
                                     ax² + bx + c = 0 
To write the equation in its general form, eliminate the decimal by multiplying the equation by 10. It now becomes,
                                        3x² + 50x - 70 = 0
The value of b is therefore 50 and the answer is the second choice.
