If y is inversely proportional to the square root of x and y=−70 when x=49, find y if x=2401.

Dahasolnce [82]

The value of y when x= 2401 is -10

<h3>How to determine the value of x?</h3>

An inverse variation is represented as:

$y = \frac{k}{\sqrt x}$

Where k is the proportionality constant

When y = -70, x = 49

So, we have:

$-70 = \frac{k}{\sqrt {49}}$

Take the square root of 49

$-70 = \frac{k}{7}$

Multiply through by 7

k = -490

Substitute k = -490 in $y = \frac{k}{\sqrt x}$

$y = -\frac{490}{\sqrt x}$

When x =2401, we have

$y = -\frac{490}{\sqrt {2401}}$

Evaluate the square root

$y = -\frac{490}{49}$

Divide

y = -10

Hence, the value of y when x= 2401 is -10

What is the equation of the line that is parallel to y-3x=2 and that passes through (6,1)?

Artemon [7]

Try this solution (analytic method):

1. if new line is parallel to the given one (y=3x+2) it means the new line has a form y=3x+b, where b - number.

2. In order to calculate 'b', it need to substitute the coordinates of point (6;1) into the equation of the new line:

1=3*6+b, ⇒ b=-17.

3. If to make up the equation of the new line:

y=3x-17
