900,000 because that is where the value of 9 is placed in the number.
        
                    
             
        
        
        
F(x) = -5x 
g(x) = 8x² - 5x - 9 
(f×g)(x) = ? 
= ((-5x)(8x²-5x-9)) 
= -40x³ + 25x² + 45x → The answer Opsi D
        
             
        
        
        
Step-by-step explanation:
Put the values of x = 6, y = -7 and z = 0.8 to the expressions:
a) 5x → 5(6) = 30
b) 3y → 3(-7) = -21
c) 10z → 10(0.8) = 8
