Answer:
Step-by-step explanation:
Let's use the addition/elimination method to solve this.  If we multiply the first equation through by -1 we can eliminate the x terms.  Doing that gives us:
  -x  +  3y  =  3
   x  +  3y  =  9
The x's subtract each other away leaving us with
6y = 12 so
y = 2.
Now we will plug in 2 for y in either of the original equations to solve for x:
x + 3(2) = 9 and
x + 6 = 9 so
x = 3
The coordinate for the solution is (3, 2) or x = 3, y = 2
The second choice down is the one you want.
 
        
             
        
        
        
Given:
Consider the below figure attached with this question.
To find:
The interpretation for x-intercept in this context.
Solution:
In the given graph x-axis represents the second since sending print job and y-axis represents the Pages printed.
At x-axis the y-coordinate is 0. It means the x-axis represents the number of seconds that passed before the printer started printing pages.
Therefore, the correct option is C.
 
        
             
        
        
        
(2/3)x = 10
(3/2)(2/3)x = 10(3/2)
x = 30/2 = 15
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
The formula of the volume of a cube is  where "a" would correspond to the length of an edge/side/height/etc.
 where "a" would correspond to the length of an edge/side/height/etc. 
If we insert our value into the formula, we get the following result:
