79.50-45 = 35.50 so she spent 35 dollars and 50 cents on jeans
 
        
                    
             
        
        
        
For this case we have that by definition, the standard form of a linear equation is given by:

By definition, if two lines are perpendicular then the product of their slopes is -1. That is to say:

We have the following point-slope equation of a line:

The slope is:

We find the slope  of a perpendicular line:
of a perpendicular line:

Thus, the equation is of the form:

We have the point through which the line passes:

Thus, the equation is:

We manipulate algebraically:

We add 3 to both sides of the equation:

We multiply by 2 on both sides of the equation:

We subtract 3x on both sides:

We subtract 12 from both sides:

Answer:
x-intercept = (-8, 0)
y-intercept = (0, -2)
Step-by-step explanation:
Given linear equation is: x + 4y = - 8
For x - intercept: Plug y = 0 in the above equation.

For y - intercept: Plug x = 0 in the given linear equation.

 
        
             
        
        
        
I would say, well, if there are 3 sides that are equal on spinner 1. They are equal. But, we are focusing on spinner two that has two sides. If there is only 2 equal sides then, they would have to be straight across from each other. So that is 180. 360 is full circle. take away 180 to get answer. 
360-180=180
I hope this helped. And sorry if it is not the correct answer. But that is how I would of answered it
