Coordinates (x, y)

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

Point (7, 0)

Equation y = x - 7

<u>Step 2: Find</u>

  1. Substitute in point [Equation]:                                                                         0 = 7 - 7
  2. Subtract:                                                                                                            0 = 0

Since 0 = 0 is true, then it would be a solution to the equation.

Find three consecutive even integers. Such that 7 times of first integer is 4 more than the sum of second and third integers
attashe74 [19]

Answer:

1st even integer = 2

2nd even integer = 4

3rd even integer  = 6

Step-by-step explanation:

Let the consecutive even integers be:

1st = 2(x)

2nd= 2(x +1) = 2x + 2

3rd = 2(x + 2) = 2x + 4

According to Given conditions:

7(2x) = 4 +  2x +2 + 2x + 4

By Simplifying:

14x = 10 + 4x

Subtracting 4x from both sides

14x - 4x = 10 + 4x -4x

10x = 10

Dividing both sides by 10 we get:

x = 1

Now putting value of x in supposed integers:

1st even integer = 2(1) = 2

2nd even integer = 2(1)+2 = 4

3rd even integer = 2(1) + 4 = 6

I hope it will help you!

Help plz consider the sequence {4,6,8,10...}Find the explicit formula that defines the sequence. A) an = 2n + 2 B) an = 2n + 4 C
Alex777 [14]

A

this is an arithmetic sequence whose n th term ( explicit formula) is

a_{n} = a_{1} + (n - 1 )d

where d is the common difference and a_{1} the first term

here d = 10 - 8 = 8 - 6 = 6 - 4 = 2 and a_{1} = 4, hence

a_{n} = 4 + 2(n - 1 ) = 4 + 2n - 2 = 2n + 2 → A
