Hi! The answer would be all real numbers!
Hope this helps! :)
 
        
             
        
        
        
If the function is: f(x) = 4^x     - 8
D = {XeR}
R = {YeR|Y≥0}
if the function is: <span>f(x)=4^(x-8)
</span>D = {XeR}
R = {YeR|Y≥ -8}
        
             
        
        
        
.35x+45=y
x is the miles they run
.35 shows that they charge 35 cents per mile 
45 is the constant or the fee they always charge to use their vehicle
        
                    
             
        
        
        
Answer:
4.75 pounds of hamburger meat
Step-by-step explanation:
In order to calculate the total amount of hamburger meat that Ben would need we would need to multiply the total number of burgers that he wants to make (19) by the amount of meat each burger will use (1/4 pound or 0.25 pound). Therefore, we would do the following...
19 * 0.25 = 4.75 pounds
Finally, we can see that Ben would need a total of 4.75 pounds of hamburger meat to make 19 equal sized 1/4 pound burgers.
 
        
             
        
        
        
The answer is B, divide the rate by the unit to simplify
