Answer:
x=14
Step-by-step explanation:
create an equation out of it. 4x+2x-6=90. Or 6x=84
 
        
             
        
        
        
Answer:
2.8
Step-by-step explanation:
using cosine rule
 =
 = 
s =  = 2.842 = 2.8
 = 2.842 = 2.8
 
        
             
        
        
        
C: 15,938 + 427 is 4 times as large as (15,938 + 427) /4 
        
             
        
        
        
Answer:
 f(x)=x-6
Step-by-step explanation:
Given : Parent function : 
To Find : If you shift the linear parent function, f(x) = x, down 6 units, what is the equation of the new function?
Solution:
Parent function : 
Shift the given function down by 6 units.
Rule : The graph f(x) shifts down by b units 
So, f(x)→f(x)-b
So, Shift the given function down by 6 units.
So, f(x)→f(x)-6
f(x)=x
So, x→x-6
So, the new function is f(x)=x-6
