Let <em>s</em> be the plane's speed in still air and <em>w</em> the wind speed. Then
<em>s</em> - <em>w</em> = (6060 km)/(6 h) = 1010 km/h
<em>s</em> + <em>w</em> = (12,150 km)/(9 h) = 1350 km/h
Adding these equations together eliminates <em>w</em> and lets you solve for <em>s</em> :
(<em>s</em> - <em>w</em>) + (<em>s</em> + <em>w</em>) = 1010 km/h + 1350 km/h
2<em>s</em> = 2360 km/h
<em>s</em> = 1180 km/h
<h3>I'll teach you how to solve 6 divided by -3/9</h3>
--------------------------------------------------------------
6 divided by -3/9
Apply the fraction rule:
- 6/ 3/9
Apply the fraction rule:
-6*9/3
Multiply the numbers:
- 54/3
Divide the numbers:
-18
Your Answer Is -18

Answer:
(6,1)
Step-by-step explanation:
1.) group the x and y terms (and move the constant to the other side)
x²-12x+y²-2y= -12
divide the coeficcents for the terms with just 1 or 1 x variable by 2 and then square it (and add that to both sides)
x²-12x+36+y²-2y+1= -12+36+1
factor
(x-6)²+(y-1)²= 25
the center is therefore (6,1)
Answer:
your answer would be the second option.
Step-by-step explanation:
How this is is because it is in simple y=mx+b formation
the b is +1 and you go down one and over to the three which is decreasing so it would be -1/3
24ab+ab-7
=25ab-7
