A sequence is created from the function k(n) = 2n + 3, where n represents the position of the term of the sequence. The sequence
pashok25 [27]
Substitute the n value into the equation. The n repersents the 'nth' term.
K (1) = 2(1) + 3
      K = 5
Therefore, when n = 1, K = 5
Same goes t any other term.

K (3) = 2(3) + 3
     K = 9
So, when n = 3, K=9

Just keep applying the same rule. Also, make sure that you answer it with a sentence at the end. This should always help you and the marker see that you are confidence with your answer...

I hoped I helped out. Good luck. :)

The manager of a furniture factory finds that it costs $2400 to manufacture 60 chairs in one day and $4800 to produce 260 chairs
tamaranim1 [39]

Answer:

C(x) = 12x + 1680

Slope = 12

Intercept = 1680

Step-by-step explanation:

Given that:

X1 = 60 chairs ; y1 = 2400

X2 = 260 chairs ; y2 = 4800

Obtain the slope ; m

m = y2 - y1 / x2 - x1

m = 4800 - 2400 / 260 - 60

m = 2400 / 200

m = 12

Using the point slope relation:

y - y1 = m(x - x1)

y - 2400 = 12(x - 60)

y - 2400 = 12x - 720

y = 12x - 720 + 2400

y = 12x + 1680

C(x) = 12x + 1680

From the general slope intercept equation :

y = mx + c

m = slope ; c = intercept

Hence,

C(x) = 12x + 1680

Slope = 12

Intercept = 1680

Can someone please help me to solve 3/4 problems pls i will mark you the brainly pls I need help
Gennadij [26K]

Answer:

3. x = 11.6

4. f = 2 g = 2

Step-by-step explanation:

3) (3x - 7) + (4x + 6) = 90 --> x = 11.6

4) 3f + 1 = 5f - 15 ---> f = 2

6g - 5 = 3f + 1

6g = 3(2) + 6 ---> g = 2
