Answer:

y = -3x + 4

Step-by-step explanation: Substitute the numbers in for x & y to see which one is the answer.

(-1, 7):

y = -3x + 4

7 = -3(-1) + 4

7 = 3 + 4

7 = 7

TRUE

(2, -2):

y = -3x + 4

-2 = -3(2) + 4

-2 = -6 + 4

-2 = -2

TRUE

(7, -17):

y = -3x + 4

-17 = -3(7) + 4

-17 = -21 + 4

-17 = -17

TRUE

(10, -26):

y = -3x + 4

-26 = -3(10) + 4

-26 = -30 + 4

-26 = -26

TRUE

Hope this helps you!!! :)

Write an<br> i explicit formula for an, the nth term of the sequence 200, 40, 8, ....

Ugo [173]

Answer:

$T_n = 200 * (\frac{1}{5})^{n-1$

Step-by-step explanation:

Given

$Sequence: 200,40,8$

Required

The nth term

The given sequence is a geometric sequence.

So, first we identify the first term

$a = 200$

Calculate common ration

$r = \frac{40}{200}$ or $r = \frac{8}{40}$

$r = \frac{1}{5}$

So, the nth term is:

$T_n = ar^{n-1$

$T_n = 200 * (\frac{1}{5})^{n-1$
