Answer:

First flight= 2, second = 4

Step-by-step explanation:

Let's say the first flight = F and the second flight = S

If the first flight is half of the second, then S = 2F

F + S = 6

That means

F + 2F = 6

3F = 6

F = 6/3

F = 2

If the first flight equals 2 hours, and it is half of the second, then S = 2F, which is 4.

2x=6
2 represents the how many flights
x represents how long each was (in hours)
6 represents the total time for each flight( in hours)

Hope this helped!!!

Answer:

Equation of line in slope-intercept form that passes through (4, -8) and is perpendicular to the graph y= \frac {2}{5} x - 3 is below

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

Step-by-step explanation:

Slope of the equation  y= \frac{2}{5} x -3   is  m_1 = \frac{2}{5}

Since slopes of perpendicular lines are negative reciprocal of each other, therefore slope of other line is given as

m_2 = - \frac {1}{m_1}  = - \frac {5}{2}

Equation of line in point slope form is given as

y-y_1=m_2(x-x_1)

Here  (x1, y1) = (4, -8)

y+8 = - \frac{5}{2} (x-4)

Simplifying it further  

y = - \frac {5}{2} x + \frac {5}{2} 4 - 8

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