One of the dots can be on (0,-4) because -4 is the y-intercept.

next can be (6.-9) because you can go rise over run or down 5 over 6

or you can go up 5 left 6 giving you (-6,1)

(0, -4) and (6, -9) are 2 points on the line.

For his mobile phone service, John pays a monthly fee of $40 plus $15 for each 1 GB of data (rounded up) over his 8 GB of data t

kolbaska11 [484]

Answer:

John can use no more than 2 GB of additional data

Step-by-step explanation:

Monthly fee = $40

Additional fee = $15 for each 1 GB of data (rounded up) over his 8 GB.

Let x be the number of additional data in GB over his 8 GB of data that comes with his plan.

Total monthly charge is

$C(x)=40+15x$

It is given that monthly charge before taxes to be at most $70.

$C(x)\leq 70$

$40+15x\leq 70$

$15x\leq 70-40$

$15x\leq 30$

Divide both sides by 2.

$x\leq 2$

Therefore, John can use no more than 2 GB of additional data.

Find the sum of the series 9+3+1+........+1/27

Elina [12.6K]

Answer:

364/27

Step-by-step explanation:

9, 3, 1, ... is a geometric sequence with common ratio r = 1/3.

The nth term is a1rn-1.

If a1rn-1 = 1/27, then 9(1/3)n-1 = 1/27

32(3-1)n-1 = 3-3

3231-n = 3-3

33-n = 3-3

3-n = -3

n = 6

The sum, Sn, of the first n terms of a geometric sequence is given by Sn = a1(1 - rn) / (1 - r).

So, 9 + 3 + 1 + ... + 1/27 = S6 = 9(1 - (1/3)6) / (1 - 1/3)

= 9(1 - 1/729) / (2/3)

= (27/2)(728/729) = 364/27
