We first need to pick the correct piece to use. In this case, we will use f(x) = -x-5 because -5<=-4.
Then, we use direct substitution:
f(-4) = -(-4) - 5
f(-4) = -1
 
        
                    
             
        
        
        
Answer:
A
Step-by-step explanation:
Just put x = 80 and y = 210 into the equation...
or put x = 40, y = 90. 
A:
210 - 90 = 3(80-40)
120 = 120√
B:
210 + 90 = 3(80+40)
300 = 360×
C:
210 - 90 = 2.6(80-40)
120 = 104×
D:
210 + 90 = 2.6(80+40)
300 = 312×
 
        
             
        
        
        
Answer: I don't know what you wanted to be solved, but, I solved for x
Step-by-step explanation:
<u>Solved for x</u>
- <u>x=(2\pm i\sqrt(6))/(2)</u>
 
        
                    
             
        
        
        
Answer:
3/8 & 4/8
Step-by-step explanation:
1/2 - 1/8 = 4/8 - 1/8 = 3/8
x - 1/8 = 3/8
x = 4/8
