Answer:

Step-by-step explanation:

-9x + 1 = - 80

Take 1 to another side and when it goes to another side it changes its sign and become -

- 9x = - 80 -1

- 9x = - 81

As we can see both sides have minus so it will be cancelled

9x = 81

x = 81/9

therefore x = 9

You are told that an is an arithmetic sequence with a3=11 and a6=17. What is a15?

bekas [8.4K]

Answer:

a15 = 35

Step-by-step explanation:

Given:

a3 = 11

a6 = 17

Find:

a15 = ?

Computation:

a3 = 11 ⇒ a+ 2d = 11..........Eq1

a6 = 17 ⇒ a + 5d = 17...............Eq2

From Eq2 - Eq1

⇒ 3d = 6

⇒ d = 2

And a = 7

So,

⇒ a15 = a + 14d

⇒ a15 = 7 + 14 (2)

⇒ a15 = 7 + 28

⇒ a15 = 35
