write out the sum using the summation notation, assuming the suggested pattern continues. -10-2+6+14+...+110
Ronch [10]
The series is an arithmetic series with first term -10 and common difference (-2-(-10))=8. The general term a_n can be written as
  a_n = -10 + 8(n-1)
or
  a_n = -18+8n

The last term corresponds to
  110 = -18+8n
  128 = 8n
  16 = n

So, the summation can be written as
S_{16}=\sum\limits_{n=1}^{16}{(-18+8n)}

For questions 10-11 if l || m, find the values of x and y.
klemol [59]

Answer:

10) 9x - 2° = 5x + 54° (corresponding angles are equal)

9x - 5x = 54 + 2

4x = 56

x = 56/4

x = 14°

10y + 6° = 9x - 2° (linear pair)

10y + 6° = 9(14)° - 2°

10y + 6° = 126° - 2°

10y + 6° = 124°

10y = 124° - 6°

10y = 118

y = 118/10

Sorry, i don't know how to do the 11th question

but hope this helps you!

IS THIS RIGHT <br> JUST ANSWER YES OR NO
Ivanshal [37]

Answer:

B

Step-by-step explanation:

x^3 + 2x^2 - 9x - 18 = x^2(x + 2) - 9(x + 2) = (x + 2)*(x^2 - 9)

(x + 2)/(x + 2)(x^2 - 9) = 1 / (x^2 - 9)

==============

1/(x^2 - 9) * (x^2 - 9)/(3x  + 1) = 1/(3x + 1)


Yes B is correct.
