The explicit formula of the sequence is given by a_n = -4n(n-1).

We have to find the first five terms of the sequence.

The first term:

\begin{gathered} a_1=-4\times(1)(1-1) \\ =-4(0) \\ =0 \end{gathered}

The second term:

\begin{gathered} a_2=-4(2)(2-1) \\ =-8(1) \\ =-8 \end{gathered}

The third sum:

\begin{gathered} a_3=-4(3)(3-1) \\ =-12(2) \\ =-24 \end{gathered}

The fourth term:

\begin{gathered} a_4=-4(4)(4-1) \\ =-16(3) \\ =-48 \end{gathered}

The fifth term:

\begin{gathered} a_5=-4(5)(5-1) \\ =-20(4) \\ =-80 \end{gathered}

Thus, option D is correct.

earnstyle [38]
For this case we have the following expression:
 (x-1) / (3) = k
 Substituting the value of k = 3 we have:
 (x-1) / (3) = 3
 From here, we must clear the value of x.
 We have then:
 x-1 = 3 * 3
 x-1 = 9
 x = 9 + 1
 x = 10
 Answer:
 
The value of x is given by:
 
x = 10

Help me please I’ll give a lot of points
Alenkasestr [34]

Answer:

21. B

22. D

23. C

24. y = 3x - 12

Step-by-step explanation:

21.  it has to be a positive slope since the graph shows it is increasing/positive slope. Has to be A or B. But it isn't A because where x = 1 1/2, y doesn't equal 0 like the graph shows.

22. It is D if you rewrite the equation starting with y=, so you subtract 2x on both sides to get y = -2x +6. Parallel means slopes are the same, so the slope has to be -2, which is D.

23. The only one that fits the description is C.

24.

in standard form, rearrange the equation so only y is on one side, the rest on the other.

-4x + 2y  = 2x - 24

first add 4x on both sides so -4x cancels out on the left hand side.

-4x + 4x + 2y  = 2x + 4x - 24

simplify it and get 2y = 6x - 24

divide both side by 2

y = 3x - 12

plot this as shown with arrows on lines.

please give thanks :)
