The answer is 2.2142857143 but you can round it to 2.
Answer:
8
Step-by-step explanation:
Solve for x:
x - 8 = 0
Hint: | Isolate terms with x to the left hand side.
Add 8 to both sides:
x + (8 - 8) = 8
Hint: | Look for the difference of two identical terms.
8 - 8 = 0:
Answer: x = 8
Your answer would be 2.6 meters per second
390 ÷ 150 = 2.6
I want to preface this by saying I don't have the answer. I haven't taken linear algebra yet. If someone here does know the answer, by all means, their answer should supersede mine. But... if
![A= \left[\begin{array}{ccc}-2&-1&0\\0&1&3\\1&1&6\\2&1&-12\end{array}\right]](https://tex.z-dn.net/?f=%20A%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-2%26-1%260%5C%5C0%261%263%5C%5C1%261%266%5C%5C2%261%26-12%5Cend%7Barray%7D%5Cright%5D)
then here is an outline of how to determine whether the columns form a linearly independent set.
one less than the 18 and a number
18 × n = (product) - 1
