Y varies with x
so y/ x = constant
so, y1/x1 = y2/x2
6/9 = 18 / x2
so x2 = ( 9*18)/6
x2 = 27
another solution
y varis with x
y inceased by 3 times
so x must increase 3 time of the intial value
x(new) = 9*3 = 27

-2(-3v-5)-5v=12(1+v)-2
Alexandra [31]
<h3>Answer:</h3>

\large\boxed{v=0}

<h3>Step-by-step explanation:</h3>

In this question, we're solving the equation by figuring out what v equals to.

We are solving:

-2(-3v-5)-5v=12(1+v)-2

Solve:

-2(-3v-5)-5v=12(1+v)-2\\\\\text{Distribute the -2 to the -3v and -5}\\\\6v+10-5v=12(1+v)-2\\\\\text{Distribute the 12 to the 1 and v}\\\\6v+10-5v=12+12v-2\\\\v+10=12+12v-2\\\\\text{Subtract both sides by 12v}\\\\-11v+10=12-2\\\\\text{Subtract both sides by 10}\\\\-11v=-10+12-2\\\\-11v=2-2\\\\-11v=0\\\\\text{Divide both sides by -11}\\\\\boxed{v=0}

When you're done solving, you should get v = 0.

This means that v = 0 would be your final answer.

Aight I think I just figured out this pyramidal sequence thing. You're going up by perfect numbers right, like 4, 9, 16, 25. Bec
muminat

Answer:  Close.  Your observation is correct. When you see that the difference between two numbers in the sequence is a perfect square, you are looking at a pyramidal sequence

1² = <u>1 </u> top of pyramid

1 + 2² = <u>5</u>   total in top 2 layers

1 + 2² + 3² = <u>14</u> total in top 3 layers

1 + 2² + 3² + 4² = <u>30</u> total in the top 4 layers.

1 + 2² + 3² + 4² + 5² = <u>55</u>  total in the top 5 layers.

Layer 6 is 6² more, 91

Layer 7 is 7² more so, 140

I think you got it.

Step-by-step explanation:  The numbers are like when you keep adding the layers in a pyramid, and the next number is the total of the previous layers plus the square of the next layer number.
