Answer:
a)
b) 
Step-by-step explanation:
From the question we are told that:
Distance 
Time of flight 
Flight back 
Generally the equation for Time for flight with jet steam is mathematically given by



Generally the equation for Time for flight against jet steam is mathematically given by



Solving equ 1 and equ 2 simultaneously


Therefore

X = 3.8
5x+1=20
Subtract 1 on both sides to get:
5x=19
Divide by 5 on both sides to get:
x=19/5
You can leave it as a fraction as 19/5, or convert to a decimal as 3.8.
-3d/(d^2-2d-8) + 3/(d-4) = -2/(d+2)
factor
-3d/(d-4) (d+2) +3/(d-4) = -2/(d+2)
multiply by (d-4)(d+2) on each side
(d-4)(d+2)[-3d/(d-4) (d+2) +3/(d-4)] = (-2/(d+2))*(d-4)(d+2)
distribute
-3d +3(d+2) = -2(d-4)
distribute
-3d +3d+6 = -2d+8
combine like terms
6 = -2d+8
subtract 8 to each side
-2 = -2d
divide by -2
1 =d
Answer:
It has a slope of 1 with a y-intercept of -4.
Step-by-step explanation:
Since the line is going in its upward direction, its rate of change has to be positive 1. In addition, the y-intercept is 4 because that is where it crosses the y-axes. The x-intercept is -4, not the y-intercept.
