Answer:

an= n * (n+1)

Step-by-step explanation:

2,6,12,20,.....

6-2 =4

12-6 = 6

So there is no common difference because these numbers are not the same

It cannot be an arithmetic difference

6/2 =3

12/6 =2

So there is no common ratio because these numbers are not the same

It cannot be geometric

2, 6, 12, 20,...

+4 +6 +8 +10

a1 =2

a2 =2*3

a3 = 2*6=2*2*3=3*4

a4=2*10=2*2*5=4*5

.....

a5 = 5*6 = 30

an= n * (n+1)

Answer:

Step-by-step explanation:

The increase would be possibly about by 100,000 dollars, but if you were to take it as a decimal as a millionth, it would go up by 10 percent.

Given the equation y = 4 + 2x find the values for y given the value xIf x = 3 then y =

If x = -3 then y =

If x = 4 then y =

If x = -2 then y =

Answers

Answer:

If x = 3 then y = 10

If x = -3 then y = -2

If x = 4 then y = 12

If x = -2 then y = 0

Y=(x-1)^2+2 find the y-intercept

Answers

Answer:

(0,3)

Step-by-step explanation:

So we have the equation:

$y=(x-1)^2+2$

Recall what the y-intercept is. The y-intercept is when the graph crosses the y-axis. Therefore, at that point, the x-value is 0. So, to find the y-intercept, substitute 0 for x. Thus:

$y=(0-1)^2+2$

Subtract:

$y=(-1)^2+2$

Square:

$y=1+2$

Add:

$y=3$

So, the y-intercept is at (0,3).

The length of a rectangle is 2 more than twice the width. The perimeter is 76 feet. Find the length and width of the rectangle.

Answers

so we can set x= width
2x+2 = length
so 2(x)+2(2x+2)= 76
so that will give us 2x+4x+4=76
6x=72
x=12
so 12 is width and 26 is length
