Let x be the smaller number and y the larger:

As the numbers are consecutive y - x = 1
And 3y + x = 31  (3 times the large added to the smaller)

From the first equation y = x + 1
By substituting:
3(x + 1) + x = 31
3x + 3 + x = 31
4x = 28
x = 7

y = x + 1
y = 7 + 1 = 8

P is inversely proportional to the cube of (q-2) p=6 when q=3 find the value of p when q is 5
sveticcg [70]
\bf \begin{array}{llllll}
\textit{something}&&\textit{varies inversely to}&\textit{something else}\\ \quad \\
\textit{something}&=&\cfrac{{{\textit{some value}}}}{}&\cfrac{}{\textit{something else}}\\ \quad \\
y&=&\cfrac{{{\textit{k}}}}{}&\cfrac{}{x}
\\
&&y=\cfrac{{{  k}}}{x}
\end{array}\\\\
-----------------------------\\\\
\textit{p is inversely proportional to the cube of (q-2)}\implies p=\cfrac{k}{(q-2)^3}
\\\\\\
now \quad 
\begin{cases}
p=6\\
q=3
\end{cases}\implies 6=\cfrac{k}{(3-2)^3}

solve for "k", to find k or the "constant of variation"

then plug k's value back to \bf p=\cfrac{k}{(q-2)^3}

now.... what is "p" when q = 5?  well, just set "q" to 5 on the right-hand-side, and simplify, to see what "p" is

Given the quadratic function g(x)=x^2, find g(3x-2).
maxonik [38]

Answer:

g(3x-2) = (3x-2)^{2}

Step-by-step explanation:

g(x)=x^{2}

To do this, you must substitute 3x-2 for x in the equation g(x)

g(3x-2) = (3x-2)^{2}

Simplified this would be

9x^{2} -12x+4
