<span>The equations that show a direct variation between x and y when solved for y are:
</span><span>A. -10+y=3x-10
B. y=-1/8x
</span>
Since k is constant (the same for every point), we can find k when given any point by dividing the y<span>-coordinate by the </span>x<span>-coordinate. For example, if </span>y varies<span> directly as </span>x , and y<span> = 6 when </span>x<span> = 2 , the constant of </span>variation<span> is k = = 3 . Thus, the equation describing this </span>direct variation<span> is </span>y<span> = 3x .</span>
answer: n=7
work:
6n-14=3n+7
6n-14 (+14) = 3n+7 (+14) add 14 to both sides
6n=3n+21
6n(-3n)=3n(-3n)+21 subtract 3 from both sides
3n=21
3n/3= 21/3 divide by 3 on both sides
n=7
