t p = through point

s = slope

y - y(t \: p) = (s) \times ( \: x - x(t \: p) \: ) \\

y - ( - 7) =  \frac{5}{2} \times (x - 4) \\

y + 7 =  \frac{5}{2} \times (x - 4) \\

y + 7 =  \frac{5}{2}x -  \frac{5 \times 4}{2} \\

y +7 =  \frac{5}{2}x -  \frac{20}{2} \\

Subtract both sides -7

y =  \frac{5}{2}x -  10 - 7 \\

y =  \frac{5}{2}x -   17 \\

And we're done....

At maximum speed, an airplane tracked 1720 miles against the wind in 5 hours. Flying with the wind, the plane can travel the sam
nataly862011 [7]
Recall your d = rt, distance = rate * time.

as the plane goes against the wind, the plane is not really flying at "x" mph, but is really going slower, at " x - y ", because the wind is subtracting speed from it.

likewise, when the plane is going with the wind, is not really going at "x" mph, but at " x + y ", is going faster due to the wind, thus

\bf \begin{array}{lccclll}
&\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\
&------&------&------\\
\textit{against the wind}&1720&x-y&5\\
\textit{with the wind}&1720&x+y&4
\end{array}
\\\\\\
\begin{cases}
1720=(x-y)5\implies \frac{1720}{5}=x-y\\\\
344=x-y\implies \boxed{y}=x-344\\
---------------\\
1720=(x+y)4\implies \frac{1720}{4}=x+y\\\\
430=x+y\implies 430=x+\left( \boxed{x-344} \right)
\end{cases}
\\\\\\
430=2x-344\implies 774=2x\implies \cfrac{774}{2}=x\implies 387=x

How many solution does an equation have when you isolate the variable and it equals a constant
RoseWind [281]

Answer:

Step-by-step explanation:

it depends. if (for example) y=x2 then there are an infinite amount of answers. if there is an equation like: If (variable X)= (variable Y) + 5 and if X=5, what is Y? then there is only one answer. check an algebra book, it can give you a more detailed answer.
