Answer: Only f(x), which is the red curve

The red curve extends infinitely in both directions left and right. Plugging any x value into the f(x) function leads to some corresponding y value. The other functions g(x) and p(x) have restricted domains. For instance, x = 4 would not work for g(x) or p(x), but it works for f(x).

What Percent Of 700 Is 385

Firlakuza [10]

$method\ \#1\\\\\begin{array}{ccc}700&-&100\%\\385&-&p\%\end{array}\ \ \ \ |cross\ myltiply\\\\700p=385\times100\\700p=38500\ \ \ \ \ |divide\ both\ sides\ by\ 700\\\\p=\frac{38500}{700}\\\\p=\frac{385}{7}\\\\\boxed{p=55\ (\%)}$

$method\ \#2\\\\\frac{385}{700}\times100\%=\frac{385}{7}\times1\%=55\times1\%=55\%$

Y is directly proportional to square root of x<br> If y=56 when x=49 find,<br> y when x=81

STALIN [3.7K]

$\qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad \stackrel{\textit{constant of variation}}{y=\stackrel{\downarrow }{k}x~\hfill } \\\\ \textit{\underline{x} varies directly with }\underline{z^5}\qquad \qquad \stackrel{\textit{constant of variation}}{x=\stackrel{\downarrow }{k}z^5~\hfill } \\\\[-0.35em] \rule{34em}{0.25pt}$

$\stackrel{\begin{array}{llll} \textit{"y" directly}\\ \textit{proportional to }\sqrt{x} \end{array}}{y = k\sqrt{x}}\qquad \textit{we know that} \begin{cases} y = 56\\ x = 49 \end{cases}\implies 56=k\sqrt{49} \\\\\\ 56=7k\implies \cfrac{56}{7}=k\implies 8=k~\hfill \boxed{y=8\sqrt{x}} \\\\\\ \textit{when x = 81, what is "y"?}\hfill y=8\sqrt{81}\implies y=8(9)\implies y=72$

Find the least common denominator for these two rational expressions.

lbvjy [14]

$\frac{y}{y^{2}-1},\ \frac{y}{y^{2}-8y+7}$
$=\frac{y}{(y-1)(y+1)},\ \frac{y}{(y-1)(y-7)}$
$=\frac{y(y-7)}{(y-1)(y+1)(y-7)},\ \frac{y(y+1)}{(y-1)(y+1)(y-7)}$

So the common denominator is $(y-1)(y+1)(y-7)$
