Answer:

a_{8} = - 14

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = - 3, thus

a_{8} = 7 + (7 × - 3) = 7 - 21 = - 14

Which ordered pair is the solution to the system of linear equations y = -7x + 2 and y = 9x - 14?
lisabon 2012 [21]
Y = -7x + 2
y = 9x - 14

-7x + 2 = 9x - 14
14 + 2 = 9x + 7x
16 = 16x
1 = x

y = -7x + 2
y = -7(1) + 2
y = -7 + 2
y = -5

solution is : (1,-5) <==
