ANSWER : (9u - 8)2
STEPS:
Step-1 : Multiply the coefficient of the first term by the constant 81 • 64 = 5184 
Step-2 : Find two factors of 5184 whose sum equals the coefficient of the middle term, which is -144 .
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -72 and -72 
 81u2 - 72u - 72u - 64
Step-4 : Add up the first 2 terms, pulling out like factors :
 9u • (9u-8)
Step-5 : Add up the four terms of step 4 :
 (9u-8) • (9u-8)
 Which is the desired factorization
        
             
        
        
        
9.66 - you just multiple 6 by 1.61
        
                    
             
        
        
        
The formula is y = mx + b when b = y-intercept and m is the slope.
Slope = Rise/Run So 1/2.
Y-Int. = The y value at which x = 0. Which is -3
The line has the formula:
Y = 1/2x - 3
Hope this helps :)
 
        
                    
             
        
        
        
Esmeralda I think it's wrong cuz it’s like the question but that's added a parentheses so I think that's wrong
        
             
        
        
        
Answer:
Step-by-step explanation:
3x > 15         2x > 12        x + 1 < 8             7x < 42 
 /3     /3        /2     /2            -1     -1             /7     /7
x > 5              x  > 6              x < 7                x < 6
