The answer is y=24x I hope this helps

where

is the angle between the vectors. You have

The vectors would be orthogonal if the dot product had been zero, but that's clearly not the case.
They would be parallel if the angle turned out to be

or

, but that's also not the case.
So the answer is neither.
Well, I that would be -210 over -70. The opposite of a number is negative when it's first positive and vise versa.
It increases then falls, so it is approximately a bell shaped curve.
Whole package weighs 20pounds
1.65 = 5pounds
0.12 = extra pound
3.45 - 1.65 = 1.80 : 0.12 = 15pounds
Adding up 15pounds and the first 5 pounds equal 20 pounds
