The answer to the above system of equations is
x = -1
y = 1
z = 3
Step-by-step explanation:
Let's multiply the first equation by 2 then subtract the 3rd equation from the first:
Now let's subtract the second equation from the first
Now let's subtract our two new equations with two variables
Let's now substitute y equals 1 into one of the new equations x - 6y = -7
Now that we have answers for x and y we can substitute them into any of the first three original equations above
Now let's check by plugging in our values x = -1, y = 1 and
z = 3 into any of the other 3 equations
Answer:
Ninety thousand, four hundred and three.
If the point is on the unit circle:
x² + (√3/3 )² = 1²
x² + 3/9 = 1
x² + 1/3 = 1
x² = 1 - 1/3
x² = 2/3 / √
x = √2/√3 · √3/√3 = √6 / 3
Answer: A ) square root (6) / 3
