Option #2
11.56 is rounded to 12 because the 6 rounds the 5 to a 6. 11.6 then rounds to 12.
First, let's re-arrange to slope-intercept form.
x + 8y = 27
Subtract 'x' to both sides:
8y = -x + 27
Divide 8 to both sides:
y = -1/8x + 3.375
So the slope of this line is -1/8, to find the slope that is perpendicular to this, we multiply it by -1 and flip it. -1/8 * -1 = 1/8, flipping it will give us 8/1 or 8.
So the slope of the perpendicular line will be 8.
Now we can plug this into point-slope form along with the point given.
y - y1 = m(x - x1)
y - 5 = 8(x + 5)
y - 5 = 8x + 40
y = 8x + 45
Answer: 60 miles
Step-by-step explanation:
Given
It takes ferry 2 hours to travel to town A and only 
to travel back to town B.
Speed of current is 
Suppose the speed of the ferry is 
mph
Distance traveled in both the cases is same, but it took more time traveling to city A that is, ferry is moving upstream and downstream for returning time.
Distance between the towns is 
<span>$84 to 12%
</span>10.08
is the answer
