Answer:
(√9)^2x-1/2 = 1/81
3^2x-1/2 = 1/(3)⁴. (as √9 = 3)
3^2x-1/2 = 3^-⁴. (as 1/a^m = a^-m)
as base are equal exponents are equal
so 3 gets cancelled out
2x-1/2 = -4
(4x-1)/2 = -4
4x-1 = -8
x = -7/4
hope this helps
Step-by-step explanation:
The key idea here is that
speed of plane in wind = (speed of plane in air) + (speed of wind)
Let be the speed of the plane in still air, and the wind speed. A tailwind blows in the same direction as the plane, so for the first leg of the trip, we have
For the return trip, the wind would blow in the opposite direction:

Answer:
-2x+14=y
Step-by-step explanation:
To find the equation of a line, you use the equation mx+b=y.
m=slope
x=x coordinate
y=y coordiante
b=y intercept
Slope:
to find the slope, you use the equation y2-y1/x2-x1
10-6/2-4
4/-2
-2
Y intercept:
-2(2)+b=10
-4+b=10
b=14
Equation: -2x+14=y
