Answer:
the possible length for x might be 20
Step-by-step explanation:
hope this helps :)
It is direct variation if x/y is a constant.
x/y = 2 / -6.6 = -1/3.3
y/x = -9.9/3 = -3.3
y/x = -6.6/ 2 = -3.3
y/x = -13.2/ 3 = -3.3
y/x = -16.2/ 3 = -3.24
So its not exactly direct variation as the last values is slightly different from the first 3.
Add 1 to both sides of the equation to get 4x = 4.
Divide both sides by 4 and <em>x = 1</em>.
Answer:
14
Step-by-step explanation:
Replace with the values
