Answer:
x = -6
Step-by-step explanation:
Here we have an equilateral triangle.  All three sides have the same length, 2.  Therefore, the interior angles are all equal to 60 degrees.
Therefore, 6 - 9x = 60, and -9x = 54.  Dividing both sides by -9 results in
x = -54/9, or x = -6.
 
        
             
        
        
        
Answer:  f(x)= 2x -3 
Step-by-step explanation:
Using the given information we can come up with two points that will be use to find the slope and y-intercept.  
If you input 0 you get -3  so the point will be (0,-3) 
If you input 7  you get 11  so the point will be (7,11) 
Now use the points to find the difference in their y coordinates and divide it by the difference in their x coordinates to find the slope. 
y coordinates:  -3 - 11 = -14 
x coordinates:  0 - 7 = -7 
   -14/-7 = 2 
Since the slope is two, we will use the slope intercept formula (y = mx +b) to find the b which is the y intercept. 
Use one of the points and input its x and y coordinates into the formula including the slope to solve for b. 
-3= 2(0) +b 
-3 = 0 + b 
 b = -3  
f(x) is the same as y in the formula, meaning that the equation will be  
  f(x) = 2x -3 
 
        
             
        
        
        
The advance tickets were 35 in number and the same day ticket will be 30 in number.
<h3>What will be the number of tickets?</h3>
To find out the number of the tickets sold we will give some notations so the notations are as follows:-
A= Cost of advance tickets=$30
S= cost of same-day ticket-=15
 Number of the advance tickets
 Number of the advance tickets
 Number of same-day tickets.
Number of same-day tickets.
The equations made by the given data will be:-

By solving the above equations:-

Hence the advance tickets were 35 in number and the same day ticket will be 30 in number.
