The answer for the exercise shown above is the first option, which is:
<span> f(x)=log(x-3) 
 The explanation is shown below:
 If you substitute the x in the function for values, you will obtain the graph attached above. As you can see on the mentioned graph, when the variable x has the value 4, the value y is 0. Therefore, you have:
 </span> f(x)=log(x-3) 
  f(x)=log(4-3) 
  f(x)=log(1)
  f(x)=0<span>
 </span>
        
                    
             
        
        
        
Answer:
$25.5
Step-by-step explanation:
Sure, so the total of the 
Item:
30 Dollars ($) 
and the discount price is 
15 percent (%)
So 30 times 0.15 because 30 is the price in total and 0.15 is the percentage but in a decimal form.
30 times 0.15 equals 4.5
4.5 is the amount that 15 % equals.
30 minus (-) 4.5 because once again the total is 30 and since we have a discount price then we minus (-) the discount price by the total and you get 
A total with the discount price as 25.5 Dollars or $25.5
Hope this helps ;)
 
        
             
        
        
        
Answer:
90° 
Step-by-step explanation:
x + 37 + 53 = 180 (ANGLE SUM PROPERTY)
x + 90 = 180
x = 180-90 
x = <u>90°</u>
