Solve the equation by completing the square. -9n^2+79+=-18n
poizon [28]
Hello,
-9n²+79=-18n
==>9n²-18n-79=0
==>9(n²-2n+1-1)-79=0
==>9(n-1)²-88=0
==>[3(n-1)-2√22][3(n-1)+2√22]=0
==>3(n-1)=2√22 or 3(n-1)=-2√22
==>n-1=2/3*√22 or n-1=-2/3*√22
==>n=1+2/3*√22 or n=1-2/3*√22

Sholpan [36]

<u>Answer:</u>

An equation that relates the speeds of the two legs of the trip

  \frac{640}{x-40}+\frac{640}{x}=4

<u>Explanation:</u>

Given, we have to use x to represent the speed on the second leg

Speed on first leg when increasing your speed by 40 mph will be (x-40)

Distance is given as 640 miles and time is calculated as  

\text { Time }=\frac{\text { Distance travelled }}{\text { speed }}

According to the question, increasing speed saved four hours

Therefore, the equation that relates the speeds of the two legs of the trip will be

\frac{640}{x-40}+\frac{640}{x}=4
