6x + 2 + 4 + 6 + 8 + 10 = 126
6x + 30 = 126
6x = 96
x = 16
Numbers are {16,18,20,*22*,24,26)
Correct answer is 22.

Answer:

fourth number in this sequence is 22.

Step-by-step explanation:

Given : The sum of 6 consecutive even numbers is 126.

To find : .what is the fourth number in this sequence.

Solution : We have given

sum of 6 consecutive even numbers is 126.

Let the 6 consecutive even numbers are = x , x +2 , x + 4 , x + 6 ,x + 8 , x + 10

According to question

Sum of all 6 numbers

x + x +2 + x + 4 + x + 6 + x + 8 + x + 10 = 126 .

On adding like terms

6x + 30 = 126 .

On subtracting both sides by 30.

6x = 126 -30 .

6x = 96.

On dividing both sides by 6

x = 16 .

Then fourth number is x + 6

16 + 6 = 22,

Therefore, fourth number in this sequence is 22.

If f(x) = x2 - 2x and g(x) = 6x + 4 for which value of x does (t +g)(x)=0

Vinil7 [7]

Answer:

-2

Assumption:

Find the value of x such that $(f+g)(x)=0$ .

Step-by-step explanation:

$(f+g)(x)=0$

$f(x)+g(x)=0$

$(x^2-2x)+(6x+4)=0$

Combine like terms:

$x^2+4x+4=0$

This is not too bad too factor on the left hand side since 2(2)=4 and 2+2=4.

$(x+2)(x+2)=0$

$(x+2)^2=0$

So we need to solve:

$x+2=0$

Subtract 2 on both sides:

$x=-2$

Let's check:

$(f+g)(-2)$

$f(-2)+g(-2)$

$((-2)^2-2(-2))+(6(-2)+4)$

$(4+4)+(-12+4)$

$(8)+(-8)$

$0$

0 was the desired output of $(f+g)(x)$ .

Mrs. Habib has 46.25 feet of border for a bulletin board for her classroom. the board is 37.5 feet tall and 8.3 feet wide. how m

Luba_88 [7]

Answer:

Mrs. Habib will have 22.25 feet of border left after she puts border around the board.

Step-by-step explanation:

You must find the perimeter of the board and subtract it from the amount of border she has to find how much she will have left after she uses it. The formula for perimeter is $P=2(l+w)$ , where $l=$ the length of the board, and $w=$ the width of the board. You will add those together and multiply them by 2 because there are 4 sides to a rectangle. That means this equation will look like:

$P=2(8.25+3.75)$

Now you can just solve for the perimeter.

$P=2(12)$

$P=24$

The perimeter is 24 feet. That means it will take 24 feet of border to cover her board. In order to find out how much she'll have left over, just subtract 24 from the total amount of border she has.

$46.25-24=22.25$

Therefore Mrs. Habib will have 22.25 feet of border left over after she covers the bulletin board.

A line has a slope of -5 and passes through the point (2, 2). What is the equation for this line?

koban [17]

To determine the equation of the line, we use the point slope form equation for this problem. It is expressed as:

y - y1 = m(x - x1)

We substitute the given values in the problem to the equation.

y - 2 = -5(x - 2)
y = -5x +10+2
y = -5x +12
