Answer:

5+9n

Step-by-step explanation:

Here, we notice that the series is in A.P. (Arithmetic Progression).

Therefore, first term a = 14

common difference d = 23 - 14 = 9

Therefore the nth term will be = a + [n -1] d

putting the values, we get

nth term = 14 + 9×[n-1]

= 14 + 9n - 9

= 5 + 9n

Answer:

a = -11, 17.

Step-by-step explanation:

-7 =  |a-3| / -2

Multiply both sides by -2:

|a - 3| = 14

So a - 3 = 14

Giving a = 17

or

a - 3 =- -14

giving a = -11.

Checking these values:

-7 = |17-3| / -2 = 14/-2 = -7  

- so a = 17 is a solution.

-7 = |-11-3| / -2 = 14/-2 = -7

so a = -11 is also a solution.

1)  The midpoint of AB for A(5, 12) and B(-4, 8) is (1/2, 10)

2) The coordinate of G will be at (-2, -20) if P (-5,10) is the midpoint of EG and E has coordinates (-8,6).

The midpoint of a line is the point that divides such a line into two equal parts.

The formula for calculating the midpoint of a line is expressed as:

[tex]M(X, Y) =(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]

1) Given the coordinates A(5, 12) and B(-4, 8).

X = (5+(-4))/2

X = (5-4)/2

X = 1/2

Get the coordinate Y

Y = (12+8)/2

Y = 20/2

Y = 10

Hence the coordinate of the midpoint of AB for A(5, 12) and B(-4, 8) is

(1/2, 10)

The formula for calculating the midpoint of a line is expressed as:

[tex]M(X, Y) =(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]

1) Given the midpoint P (-5, 10) and the coordinate  (-8, 6)

Get the X coordinate of G

X = (x1+x2)/2

-5 = (x1-8)/2

-10 = x1 - 8

x1 = -10 + 8

x1 = -2

Get the Y coordinate of G

Y = (y1+y2)/2

10 = (y1+8)/2

20 = y1+8

y1 = 20-8

y1 = 12

Hence the coordinate of G will be at (-2, -20)

Answer:

Step-by-step explanation:

The direct proportion equation is ...

  y = kx

where k is the constant of proportionality. Here, you're told k=-2, so the equation is ...

  y = -2x

For x=8, the value of y is ...

  y = -2(8) = -16 . . . . . do the multiplication

For y = -20, the value of x is ...

  -20 = -2x

  10 = x . . . . . . . . . divide both sides by -2

Answer:

-16 & 40

Step-by-step explanation:

When x = 8

y = -2 × 8

y = -16

When y = -20

x = -2 × -20

x = 40

Answer:

(-12, -20).

Step-by-step explanation:

A dilation of factor 4 moves (-3, 5) to (-3*4, 5*4) = the point (-12, 20).

A reflection  over  the x-axis is (x, y) ------> ( x, -y).

So ( -12, 20) goes to (-12, -20).

The answer is C

Answer:

x = 2

Step-by-step explanation:

5-2x = -4x+9

5+(-2x+4x) = (-4x+4x)+9      [Add 4x to each side to get ride of 4x on the right]

5+2x = 9

(5-5)+2x = (9-5)     [subtract 5 from both sides to get rid of 5 on the left]

2x = 4

2x/2 = 4/2     [Divide each side by 2 to get x alone]

x=2

The solution to the equation 5 - 2x = -4x + 9 is x = 2.

Here, we have,

To solve the equation 5 - 2x = -4x + 9 step by step, we will combine like terms and isolate the variable x.

Here's how:

Start by simplifying both sides of the equation by combining like terms:

5 - 2x = -4x + 9

The left side has no like terms to combine, so we move to the right side:

-2x + 4x = 9 - 5

Simplifying further:

2x = 4

Now, we want to isolate the variable x.

To do that, we need to get rid of the coefficient 2 that is multiplied by x.

We can achieve this by dividing both sides of the equation by 2:

(2x)/2 = 4/2

Simplifying further:

x = 2

We have found the solution for the variable x.

Therefore, the solution to the equation 5 - 2x = -4x + 9 is x = 2.

Answer:

C

Step-by-step explanation:

-x+3/7=2x-27/5

Just bring all the x together, ad all the numbers together

-x - 3x = - 3/7 - 27/5

-4x = - 15/ 35 - 189/35

-4x = - 204 /35

4x = 204/35

x = 204 / 140

x = 1.457
