Sqrt(80) = Sqrt(16) x sqrt(5)
= 4 x sqrt(5)
Answer:

Step-by-step explanation:
Slope Formula: 
Simply plug in 2 coordinates into the slope formula to find slope <em>m</em>:



The 4 litres of red has to be 2 parts of the mixture, so each part will be 2 litres. Therefore 3 parts of cream will be 6 litres and the one part of blue will be 2 litres.
(2,4) and (5,13) is m=-1/3 and (4,5) and (9,-3) is m=-8/5
Answer:
y = ±√(x − 16)
Step-by-step explanation:
y = x² + 16
To find the inverse, switch x and y, then solve for y.
x = y² + 16
x − 16 = y²
y = ±√(x − 16)
