This is an equality. There is no answer, by only using the given information, that can be found for "x".
Answer:
x = - 27/5
Step-by-step explanation:
Commutative Property
2x - 12x + 36 = 90
Combine like terms
-10x + 36 = 90
subtract 36 from both sides
-10x = 90 - 36
subtract numbers
10x = 54
Divide both sides by 10
x = - 27 / 5
Answer:
The conclusions that can be made about the series [infinity] 8 cos(πn) n n = 1 and the Integral Test
IS
The Integral Test can be used to determine whether the series is convergent since it does not matter if the function is positive or decreasing on [1, [infinity])
Step-by-step explanation:
The integral test can be used to test a convergence or divergence of an harmonic series.
If the integral has a definite limit on [1, Infinity], the series is said to CONVERGE. Otherwise, it DIVERGES. It does not matter whether the function is positive on decreasing on [1, Infinity]
If the integral of the function 8 cos(πn) n, over n =[1, Infinity] has a limit, the Integral test will for for its convergence. The function been positive or decreasing on n = [1, Infinity] notwithstanding.
