Answer:
f(x)=1/2x-5
Step-by-step explanation:
first f(0)=-5 is the y intercept and then you can find the slope using those two points to then find the slope intercept equation y=mx+b
 
        
             
        
        
        
Range: maximum - minimum 
IQR: third quartile - first quartile 
median: middle number once all numbers are put in numerical order 
        
             
        
        
        
The addition property of equality justifies this. You could also say that she simply subtracted 7, and then it would be the subtraction property of equality. This is the case because if you add or subtract (or multiply or divide) the same number on both sides of an equation, the equation will still be the same. 
Hope it helps!
        
             
        
        
        
To answer this you will need to determine which area made with the 12 square tiles would give the shortest perimeter. 
Think of all the combinations to get 12 square inches
1x12, 2x6, and 3x4. The perimeters of these are 26 in, 16 in, and 14 in.
You should arrange your tiles using the 3 x 4 option. You would need 14 stones.
        
             
        
        
        
Answer:
 5 3/4 cups of cheese used for the pizza
Step-by-step explanation:
7 3/4 = 31/4 cups cheese to start
