-2, 7, 16 ..... Determine the general rule (Tn) for this sequence ​

Answers

Answer:

It is Tn = 9n - 11

Step-by-step explanation:

It is an arithmetic progression:

[tex]T_{n} = a + (n - 1)d[/tex]

a is the first term, a = -2

n is number of terms

d is common difference, d = 7-(-2) = 9

[tex]T_{n} = - 2 + \{ (n - 1) \times 9 \} \\ T_{n} = - 2 + 9n - 9 \\ T_{n} = - 11 + 9n \\ T_{n} = 9n - 11[/tex]

Answer:

[tex]T_{n}[/tex] = 9n - 11

Step-by-step explanation:

There is a common difference between consecutive terms, that is

7 - (- 2) = 16 - 7 = 9

This indicates the sequence is arithmetic with nth term

[tex]T_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 2 and d = 9 , then

[tex]T_{n}[/tex] = - 2 + 9(n - 1) = - 2 + 9n - 9 = 9n - 11

You start at (-4, -5). You move up 5 units. Where do you end?

Answers

Answer:

Step-by-step explanation:

Moving up 5 units means moving 5 positive units in the y axis.

-5 + 5 = 0.

Therefore, you end up in (-4,0)

Why is speed not important in math ?

Answers

Because if you do a work to fast your teacher will attached new work
Speed is helpful, but it is more important to have a deep understanding on the concepts than to have a fast working ability without understanding.

Since everything in math is interconnected, the deeper your understanding of the foundational topics you learn, the more easily you’ll understand new concepts that build upon the foundations.

As a concept, speed or rates of change are a key topic in Calculus. So speed is also important that way too.

2x-ky=14 and 5x-2y=5
In the system above, k is a constant and x and y are variables For what values of k will the system of equations have no solution.​

Answers

Answer:

Step-by-step explanation

In these type of questions we can use a trick to find answer

let's say we have two linear equation

1) ax+by+c=0

2)mx+ny+t=0

if  a/m = b/e ≠ c/f  that means we don't have any solution for these two equations ( that's because of analitic geometry)

so,

2x-ky-14=0

5x-2y-5=0

2/5=k/2≠14/5  k=5

If k is 4/5, the system of equations will have no solution because the lines are parallel.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The system will have no solution if the two equations represent parallel lines, because parallel lines do not intersect.

To determine if the lines are parallel, we can compare the slopes of the two lines.

The slope of the first line is 2, since it is the coefficient of x when we solve for y:

2x - ky = 14

ky = 2x - 14

y = (2/k)x - 14/k

The slope of the second line is 5/2, since it is the coefficient of x when we solve for y:

5x - 2y = 5

2y = 5x - 5

y = (5/2)x - 5/2

Therefore, the two lines are parallel if the slopes are equal:

2/k = 5/2

4 = 5k

k = 4/5

So, if k = 4/5, the system of equations will have no solution because the lines are parallel.

x = 18°

Step-by-step explanation:

∠AOB and ∠BOD form linear pair of angles, so they are supplementary, i.e., their sum is 180°.

130° + (2x + 14)° = 180°

=> 130° + 2x° + 14° = 180°

=> 2x° = 180° - 130° - 14°

=> 2x° = 36°

=> x = 36°/2°

=> x = 18°

x=18 degrees
