Step-by-step explanation:
   5       =     12          Cross multiply 
2.35             x
5x = 28.2            Divide 5 on both sides to isolate the variable
x = 5.64

Answer:
a) 
b) The inverse function is a reflection of the original function across the line 
y = x. For example, if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x. So you would use it to find the x-value at a y just like you use the original to find the y value at an x. 
Step-by-step explanation:
To do an inverse of a function you first switch the independent variable (d) and the dependent variable (c).
d = 0.45c + 5.50
Then you solve for c
d - 5.50 = 0.45 c
c = (d-5.50)/0.45
 
        
             
        
        
        
Answer:
Correct choice is B
Step-by-step explanation:
For the numbers -1 and 59, find the difference 59-(-1):
since 59-(-1)=60 and  (two arithmetic means tells you there will be three intervals), two arithmetic means will be
 (two arithmetic means tells you there will be three intervals), two arithmetic means will be 
The only correct sequence is -1, 19, 39, 59.
 
        
                    
             
        
        
        
4n+8=2(n+6)
Now isolate the n on one side of the equation:
4n+8=2n+12(distribution of the 2)
4n=2n+4(combine like terms)
2n=4(combine like variables)
N=2(isolate the n)
The answer is 2 
Good luck!
