Answer:

<h3>
<em><u>x=3 or x=-10</u></em> is the right answer.</h3>
Answer:
3mph
Step-by-step explanation:
Boat speed x
current speed 2
against current x-2 mph
with current x+ 2 mph
Distance= 5 miles
Time against + time with = 6 hours
5 /( x + 2 ) + 5 /(x - 2 ) = 6
LCD = (x - 2 ) ( x + 2 )
5 *( x - 2 ) + 5 (x + 2 ) = 6
5 x - 10 + 5 x + 10 = 6 ( x ^2 - 4 )
10 x = 6 x ^2 - 24
6 x ^2 - -10 x - 24
Find the roots of the equation by quadratic formula
a= 6 , b= -10 , c= -24
b^2-4ac= 100 + 576
b^2-4ac=676
x1=(10+26)/12
x1=3
x2=(10-26)/12
x2= -1.33
Ignore negative value
Speed of boat is 3 mph
If you <em>deposit</em> $35, you can imagine drawing a green line (representing the money gained) to the 35 on the number line, which can be seen as <em>moving </em>35 to the right<em />. Fo <em>w</em><em>ithdrawing, </em>imagine drawing a red line back 50 notches on the number line (representing money lost). The net effect that the deposit and withdrawal will have on your account balance is a

dollar <em>loss</em>, which can be represented on the number line as a line drawn to the point -15.
