Take the .5 of the 17.5 and convert it to a fractin.
we know .5 is equal to 50% or 1/2 
now we have a mixed number  

in order to convert it into an improper fraction you need to multiply the whole number by the denominator and then add the numerator all while keeping the denominator constant. 

so 
 
 
        
        
        
Answer:
y=120x
Step-by-step explanation:
You can just divide all of the points (y/x) and they all equal to 120. And when you add it to the equation its y=120x

Answer:
(-4,4)
Step-by-step explanation:
-5x-10y=-20
10x+10y=0
divide both sides by 2 
-5x-10y=-20
5x+5y=0
that makes 
-5y=-20 
divide both sides by -5
y=4
now substitute 4 for y 
10x+10 x 4=0
multiply
10x+40=0
subtract 
10x=-40 
divide 
x=-4
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Absolute Value. Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative. The absolute value of 2 + 7 is 5.
Has two solutions x = a and x = -a because both numbers are at the distance a from 0. ... An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.
