the first answer would be correct
Subtract 4y from both sides of the equation. X + 4y = 0 The answer is x = -4y
Divide each term in 20y = - 5x by 20 and simplify, the answer is y = - x/4
Subtract 4y from both sides of the equation so the answer to X+4y =0 by solving the equation for X is X= - 4y

Step-by-step explanation:
There are 11 members in the club.
President can be chosen in 11 different ways, then 10 members left.
Vice President can be chosen in 10 different ways, then 9 members left.
Secretary can be chosen in 9 different ways.
Thus, President, Vice President, and Secretary be chosen in
different ways.
<h3>Geometric mean of 5 and 7 is 5.9161</h3>
<em><u>Solution:</u></em>
Given that,
We have to find the geometric mean of 5 and 7
The geometric mean of two numbers a and b is the square root of product of a and b
Which means,
<h3><u>Geometric mean of 5 and 7</u></h3>
Thus geometric mean of 5 and 7 is 5.9161
