Answer:
59
Step-by-step explanation:
2x+2 = 120 because they are vertical angles
2x = 118
x = 59
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:

Given integral:



Using <u>integration by parts</u>:


Therefore:





Therefore:



Divide both sides by 2:

Rewrite in the same format as the given integral:

If you move the negative on the left side of the second equation over to the right side, then we can see that the equation is equivalent to 

.
Remember that an equation 

 represents a line with slope 

 and y-intercept 

. Since both equations given have a slope of -2, but have different y-intercepts, they are 
parallel.
