Answer:
When f(n) = 12, what is the value of n? Answer: n=5
Step-by-step explanation:
Answer:
All of them
Step-by-step explanation:
x² - x - 2
(x + 1)(x - 2)
x² + x - 2x - 2
x² - x - 2
(x - 0.5)² - 2.25
x² - 2(x)(0.5) + 0.5² - 2.25
x² - x + 0.25 - 2.25
x² - x - 2
The answer is x-3y=-12 use math-way for this
The first equation, 27 - 9x = - 7y, is equivalent to => 27 + 7y = 9x
The second equation is 45 +7y = 9x
You can see that thas system has not solution.
Those expressions represent parallel lines, so they never intercept each other, which means there is not solution.
Also you can subtract the two equations and get::
27 + 7y - 45 - 7y = 9x - 9x
=> 27 - 45 = 0
=> 27 = 45 which means the system has no solutions.
Answer: the system does not have any solution.
The answer is 110.5 as 221/4 is 55.25 so double that u will get 110.5 or if anything can do half of 221 which would be 110.5
