The surface elevation of Lake Powell is decreasing at the rate of 77.2 feet per year.
<h3>What is the rate(slope) at which the sea is decreasing?</h3>
The rate at which the surface elevation of the Lake Powell is decreasing can be determined by calculating the slope(steepness) of the sea.
The slope can be given as:
Slope (Δm) = rise/run
Slope (Δm) = Δy/Δx
slope (Δm) = y₂ - y₁/x₂-x₁
slope (Δm) = 3263.4 - 3881/2006-1998
slope (Δm) = -617.6/8
slope (Δm) = -77.2
Therefore, we can conclude that the surface elevation of Lake Powell is decreasing at the rate of 77.2 feet per year.

Answer:
k= 5b-3/
4
Step-by-step explanation:
3−3k+7k=5b
(Combine −3k and 7k to get 4k.)
3+4k=5b
(Subtract 3 from both sides)
4k=5b−3
(Divide both sides by 4.)
k= 5b-3/
