Well a debit card is the card that draws money directly out of your bank account, A credit is the money your going to have to pay back with interest so your best option would be B)
        
             
        
        
        
Answer:
3:1 or 3
Step-by-step explanation:
 the left triangle is scaling up to the right triangle. 5/15 is 1/3
7/21 is 1/3
4/14 is 1/3
since it is scaling UP, the scale factor is 3:1 
 
        
             
        
        
        
Answer: Oslo was colder
Step-by-step explanation: The other one was -5 and this won is -12 so Oslo is colder!! Hope it helped! :)
 
        
             
        
        
        
y = mx + b
m = slope and b = y-intercept
We can arrange 6y = x - 12 in the form of y = mx + b
                   6y = x - 12
                     y = 1/6(x) - 2
Slope of y = 1/6(x) - 2 is 1/6. Taking the negative reciprocal of the slope we get the slope for the perpendicular line.
Negative reciprocal of 1/6 is -6.
The equation for the perpendicular line is 
                   y = -6x + b
To find b we can plug in the x and y values of (4,-4) into it since it passes through those coordinates
                 -4 = -6(4) + b
                  b = -4 + 6(4)
                  b = -4 + 24
                  b = 20
So the equation for the perpendicular line is y = -6x + 20
