(-12 - 8)/(6 - 8) = -20/-2 = 10.
It's positive.
against wind the speed = x-y
distance traveled = 2460
2460/x-y= 6
6x-6y= 2460
x-y=410...........1
..
with wind speed = x+y
distance is same 2460
2460/x+y=5
5x+5y=2460
x+y=492............2
..
Add equation 1 & 2
x-y+x+y=410+492
2x=902
x= 451 mph speed of plane in still air.
..
Plug the value of x in equation 1
451-y=410
y=451-410
y=40 mph the speed of wind

Answer:
The x-intercepts of f(-x) are -6 and -5
Step-by-step explanation:
we know that
The x-intercepts of f(x) are
x=5, x=6
That means
x-5=0
x-6=0
Substitute the variable x by -x
-x-5=0 ----> x=-5
-x-6=0 ----> x=-6
therefore
The x-intercepts of f(-x) are -6 and -5

Answer:
∠C (Interior) =78°
∠B (Interior) = 62°
Step-by-step explanation:
Given:
∠A (Interior) = 40°
∠C (exterior) = 102°
Computation:
∠C (Interior) = 180° - 102°
∠C (Interior) =78°
∠B (Interior) = 180° - ∠A (Interior) - ∠C (Interior)
∠B (Interior) = 180° - 78° - 40°
∠B (Interior) = 180° - 118°
∠B (Interior) = 62°
