Work Shown:

S = sum of the first n terms of an arithmetic sequence

S = (n/2)*(firstTerm + nthTerm)

S = (8/2)*(firstTerm + 8thTerm)

S = 4*(6 + 46)

S = 4*52

Given that y varies directly with x in the table, find the<br> value of y if the value of x is 5.

Talja [164]

We know that this ratio is directly because the two magnitudes go up.

In this case we will get the <u>proportionality constant</u> by dividing any term of the second magnitude by the first.

<h3>For example: </h3>

$9 \: \div \: 3 \: = \: \boxed{3}$

Now that we know that k = 3, we can know how much "<u>y</u>" will be if <em>x = 5</em>.

We just multiply:

$3 \: \times \: 5 \: = \: \boxed{ \bold{ 15}}$

<h3>Answer: <u>y = 15</u></h3>

mixer [17]

3x+12-2x=x+12
3x-2x+12=x+12
1x+12=x+12
x+12=x+12
