Answer:
he filled 10 bags on sunday
Step-by-step explanation:
if each bag weighs 5 pounds, and he filled 2 on Saturday he used 10 pounds already. that would leave 20 pounds left, 20 ÷ 2 = 10
 
        
             
        
        
        

When variables with exponents are divided by each other, you subtract the exponents.
For example:


 
        
             
        
        
        
(-8, -5)
To form a rectangle, all the lines must be perpendicular and parallel. If you draw out the points on a coordinate plane then you can find the answer pretty easily. 
Also, this one is easy because all the lines are vertical or horizontal, and when that is the case then you can just see which number in the set hasn't appeared twice (1 appeared twice as an <em>x</em> value, 0 appeared twice as a <em>y </em>value, but -8 has only appeared once as an <em>x</em> and -5 has only appeared once as a <em>y </em>value)
        
             
        
        
        
Answer:
Step-by-step explanation:
Put the ordered pairs into the slope formula x=y2-y1/x2-x1 then you will get your slope of the line. once you have your slope pick an ordered pair and put it in point slope y-y1=m(x-x1) distribute and you will get your answer.
