Answer:
a = 10, b = -12
Step-by-step explanation:
4+2(5x-8) = ax +b
4 + 10x - 16 = ax + b
10x - 12 = ax + b
Infinitely many solutions when:
a = 10
b = -12
 
        
                    
             
        
        
        
Answer:
1) 11
2) 2 
 
3) 
4) 
5) -2
6) 
Step-by-step explanation:
1) 2 + 3
 + 3 -
 - 
=(2 × 2 )+ (3 × 4
 )+ (3 × 4 ) - 5
) - 5
= 4 + 12
 + 12 - 5
 - 5
= 11
2) 4 -2
 -2 +
 + 
= (4 × 2 ) - (2 × 7
) - (2 × 7 ) + 8
) + 8
= 8 - 14
 - 14 +8
 +8 
 
= 2 
 
3) 5 - 3
 - 3
= 5×  - 3×
 - 3× + 4×
 + 4× + 2×
 + 2×
= 
= 
4) 
= 
= 
5) 
= 
= -2
6) 
= 
= 2× - 2×
 - 2× -
 - 
= 
= 
Hope the working out is clear and will help you. :)
 
        
                    
             
        
        
        
We are given that the titanic is found 3,797 m below sea level. This is simply equivalent to 3.797 km or 3.8 km when rounded off to one decimal.
We should take note that the letter k in km means kilo and a kilo is equivalent to 1000. So this means that for 1 km there is exactly 1000 m. So to convert, simply multiply a value with unit m with this conversion factor. Conversion factor = 1 km / 1000 m
Depth of titanic = 3,797 m (1 km / 1000 m)
Depth of titanic = 3.797 km = 3.8 km
