Answer with Step-by-step explanation:

a)3n + 4 \\  \\n = 1 \\ 3 \times 1 + 4 \\ 3 + 4 \\  =7 \\  \\ n = 2 \\ 3 \times 2 + 4 \\ 6 + 4 \\  = 10 \\  \\ n = 3 \\ 3 \times 3 + 4 \\ 9 + 4 \\  = 13 \\  \\ n = 4 \\ 3 \times 4 + 4 \\ 12 + 4 \\  = 16 \\  \\ n = 10 \\ 3 \times 10 + 4 \\ 30 + 4 \\  = 34 \\

So in this sequence,

1st term = 7

2nd term = 10

3rd term = 13

4th term = 16

10th term = 34

b)4n - 5 \\  \\ n = 1 \\ 4 \times 1 - 5 \\ 4 - 5 \\  =  - 1 \\  \\ n = 2 \\ 4 \times 2 - 5 \\ 8 - 5 \\ =  3 \\  \\ n = 3 \\ 4 \times 3 - 5 \\ 12 - 5 \\  = 7 \\  \\ n = 4 \\ 4 \times 4 - 5 \\ 16- 5 \\  = 11 \\  \\ n = 10 \\ 4 \times 10 - 5 \\ 40 - 5 \\  = 35

In this sequence,

1st term = -1

2nd term = 3

3rd term = 7

4th term = 11

10th term =35

Carla pays $20 per month for her phone service, plus $0.08 for each long
Kisachek [45]

Answer:

Slope = 0.08 dollars per minutes.

Step-by-step explanation:

Carla pays $20 per month for her phone service, plus $0.08 for each long-distance minute used.

Therefore, if Carla talks for m minutes in the long-distance call, then the situation can be modeled by the equation  

C = 20 + 0.08m ............ (1), where C is the total cost for her phone service per month.

Here, 20 is the fixed price and 0.08m is the variable price for her phone charges.

This equation (1) represents a straight line with y-intercept as 20 and the slope as 0.08, where m plotted along x-axis and C is plotted along the y-axis. (Answer)
