F^1(x)=2x-16 To find the interverse interchange the variable and solve for y
 
        
        
        
The given terms can be divided into two sections. First section is for the numbers and the second one for the letters.
1st section:    1, 2, 3, and 4
2nd section:    I, L, F
I is the 9th letter in the alphabet, L is the 12th letter, and F is the 6th letter in the alphabet. 
The pattern observed:
                    I to L:    12 - 9 = 3
                    L to F:    6 - 12 = -6
Next letter should be +9. This means that the letter should be 9 places higher than F. The letter should be O which is the 15th letter. 
        
             
        
        
        
Answer:
660
Step-by-step explanation:
First, to find out how much money they have collected so far, you need to add 7100 + 1300 which is 8400. 8400= $8.40. So now you know that they have collected 8.40, you need to subtract 1500-840 which = 660
Hope this helps!
 
        
                    
             
        
        
        
Answer:

how i figured this out was not by using the table, but you can use the table
i just asked myself what two numbers multiplied together has a product of -12, one number must me negative
the two numbers must also add up to -4, meaning the bigger number had to be negative
the only answer that worked was 2 and -6
 
        
             
        
        
        
Answer:
As an equation: 15 × x = -75
Solved: x = -5
Step-by-step explanation:
15*x = -75
 =
 =  , Divide by 15 on both sides to solve for x
, Divide by 15 on both sides to solve for x
x= , The 15 in the numerator cancels out with the denominator
, The 15 in the numerator cancels out with the denominator
x= -5, because 75/15=5
