According to the graph, what is the value of the constant in the equation below?
Answers
well, let's take a look at the graph hmmmm as "x" is moving further towards the right, the line is going down, or namely "y" is lessening and lessening, which is another way to say that "y" is inversely proportional to "x".
well, we know a few points on the line hmmm let's use say hmm (10 , 8) to get the constant of proportionality. Any point will do btw, we're just using this one.
[tex]\qquad \qquad \textit{inverse proportional variation} \\\\ \textit{\underline{y} varies inversely with \underline{x}} ~\hspace{6em} \stackrel{\textit{constant of variation}}{y=\cfrac{\stackrel{\downarrow }{k}}{x}~\hfill } \\\\ \textit{\underline{x} varies inversely with }\underline{z^5} ~\hspace{5.5em} \stackrel{\textit{constant of variation}}{x=\cfrac{\stackrel{\downarrow }{k}}{z^5}~\hfill } \\\\[-0.35em] \rule{34em}{0.25pt}[/tex]
[tex]\stackrel{\textit{"H" varies inversely with "w"}}{H=\cfrac{k}{w}}\qquad \textit{we know that} \begin{cases} H=8\\ w=10 \end{cases} \\\\\\ 8=\cfrac{k}{10}\implies \boxed{80=k}[/tex]

Original options: -2 2/3 --> -2.43 --> 2.045 --> 2 5/9
Step-by-step explanation:
It will help to make all of the numbers the same, into all fractions or all decimals, so you can compare them easier. I will make them decimals.
-2 2/3 --> -2.6666... (the 6s don't end)
-2.43
2 5/9 --> 2.5555... (the 5s don't end)
2.045
You can easily split the options in half, as the top two are both negative and the bottom two are positive. So you have to figure it out amongst the two groups.
From least to greatest: -2.666 --> -2.43 --> 2.045 --> 2.555
